ItAAAASA Close to the desired solution was prepared, and then use the reference material (or another material standard) to determine its exact concentration. This determines its exact concentration is called calibration. For example, for the preparation of 0.1mol ? L-1HCl standard solution, first with a certain amount of concentrated HCl diluted with water, mixed concentration is about 0.1mol ? L-1 in dilute

solution, and then use the anhydrous Na2CO3 benchmark solution titration accurately weigh the material until both quantitative response fully, and then consumed in the titration of aqueous solution of HCl volume and quality of anhydrous Na2CO3, calculate the exact concentration of the HCl solution. Most accurate concentrations of the standard solution are determined by calibration of the method. Constant component in the determination of standard solution concentration range of 0.01 mol ? L-1-1 mol ? L-1, typically according to the components to be tested to select the height of the size of standard solution concentration. In order to improve the accuracy of calibration, calibration should pay attention to the following points: ? determination of calibration should be parallel 3-4, repeated at least three times, and called for determination of the relative deviation is less than 0.2%. ? in order to reduce measurement error, weighing the baseline amount of substance should not be too few, weighing at least 0.2G above; same titration at the end consumption of standard solutions or too small in size, the best is 20mL. C preparation of calibration solutions and use liquor, such as glassware, such as volumetric flasks and pipettes, where necessary, corrected volume, and considering the effect of temperature. D calibration good of standardOperated by stock solution was prepared solution, in principle only be diluted once, if necessary, dilute the secondary. Dilution of too many accumulated error is too large, affect the accuracy of the results. 2. calibration cannot be directly made accurate concentrations of the standard solution, first solution was

prepared, and then select the base material calibration. Do the

titration with acid and alkali solution, it is usually prepared with about 0.1mol ? The concentration of L-1. Of solid acid and alkali

solution prepared from original, generally only accurate to 1~2 significant figures, it can be graduated cylinders measuring liquids or solid reagents weigh in the scales, add the solvent (water), graduated cylinder or measuring cup amounts. But in the whole process of

calibration solution, everything is very strict and accurate. Weighing standard substances requires the use of analytical balance, accurate to four digits after the decimal point. Volume calibration solution, if it were to participate in the concentration are calculated using volumetric flasks, pipettes, burets accurate operation, not sloppy. (B) the general solution preparation and preservation methods of 1:1 (or 1+1), 1:2 (1+2) volume is expressed as concentration. For example, 1:1 solution of H2SO4, the original concentrated H2SO4 volume 1 volume, mix with 1 volume of water. And as 1:3 HCl, the original volume 1 volume hydrochloric acid

and three volumes of water and mix. Preparation of solution, according

to the requirements on the accuracy of solution concentration should be determined on the balance at the level of the weighing; record should be written to several significant figures; the prepared solution choose

what kind of vessel. That accurate, it should be very strict tolerances can be less stringent. The "quantity" concept

ItAAAASA Close to the desired solution was prepared, and then use

the reference material (or another material standard) to determine its exact concentration. This determines its exact concentration is called calibration. For example, for the preparation of 0.1mol ? L-1HCl standard solution, first with a certain amount of concentrated HCl diluted with water, mixed concentration is about 0.1mol ? L-1 in dilute solution, and then use the anhydrous Na2CO3 benchmark solution titration accurately weigh the material until both quantitative response fully, and then consumed in the titration of aqueous solution of HCl volume and quality of anhydrous Na2CO3, calculate the exact concentration of the HCl solution. Most accurate concentrations of the standard solution are determined by calibration of the method. Constant component in the determination of standard solution concentration range of 0.01 mol ? L-1-1 mol ? L-1, typically according to the components to be tested to select the height of the size of standard solution concentration. In order to improve the accuracy of calibration, calibration should pay attention to the following points: ? determination of calibration should

be parallel 3-4, repeated at least three times, and called for determination of the relative deviation is less than 0.2%. ? in order to reduce measurement error, weighing the baseline amount of substance should not be too few, weighing at least 0.2G above; same titration at the end consumption of standard solutions or too small in size, the best is 20mL. C preparation of calibration solutions and use liquor, such as glassware, such as volumetric flasks and pipettes, where necessary, corrected volume, and considering the effect of temperature. D calibration good of standardOperated by stock solution was prepared solution, in principle only be diluted once, if necessary, dilute the secondary. Dilution of too many accumulated error is too large, affect the accuracy of the results. 2. calibration cannot be directly made accurate concentrations of the standard solution, first solution was prepared, and then select the base material calibration. Do the

titration with acid and alkali solution, it is usually prepared with about 0.1mol ? The concentration of L-1. Of solid acid and alkali solution prepared from original, generally only accurate to 1~2 significant figures, it can be graduated cylinders measuring liquids or solid reagents weigh in the scales, add the solvent (water), graduated cylinder or measuring cup amounts. But in the whole process of calibration solution, everything is very strict and accurate. Weighing standard substances requires the use of analytical balance, accurate to four digits after the decimal point. Volume calibration solution, if it were to participate in the concentration are calculated using volumetric

flasks, pipettes, burets accurate operation, not sloppy. (B) the general solution preparation and preservation methods of 1:1 (or 1+1), 1:2 (1+2) volume is expressed as concentration. For example, 1:1 solution of H2SO4, the original concentrated H2SO4 volume 1 volume, mix with 1 volume of water. And as 1:3 HCl, the original volume 1 volume hydrochloric acid

and three volumes of water and mix. Preparation of solution, according

what kind of vessel. That accurate, it should be very strict tolerances can be less stringent. The "quantity" concept
