Poor shy Shirley still took the smallest loaf. When she got home, her mother cut the bread open. Many new shining pieces of silver fell out of it. Her mother was very surprised and said, "Take the money back to the good gentleman at once, for it must have got into the loaf by accident. Be quick, Shirley! Be quick!"But when the little girl gave the rich man her mother's message, he said, "No, no, my child. It was no mistake.

【提出问题】上述酚酞试液变红、红色又消失的原因是什么?【作出猜想】小李:可能是个偶然现象。
小王:可能是浑浊液中的固体氢氧化镁使酚酞试液变红,氢氧化镁沉降后溶液就变无色。
小胡:可能是酚酞试液与空气中的氧气反应,使红色消失;也可能是氢氧化镁溶液与空气中的二氧化碳反应的缘故。
小翠:可能是在热水中氢氧化镁的溶解度大,溶液中OH一离子较多,使酚酞试液变红;过一会儿温度降低,氢氧化镁的溶解度减小,溶液中OH一离子变少,酚酞试液又变无色。
