Answer» 1. Sour substances are acidic in nature,i.e, they have acids in them. So, when they are kept in brass or copper vessels, they react with them and form poisonous or better to say toxic elements which may prove harmful for the human body. So they are not kept in metal containers. 2. When acid is dissolved in water it dissociates into ions thus it conducts electricity due to the presence of ions. But alcohol is a very weak acid does not dissociate into ions and so it does not conduct electricity. Glucose, when dissolved in water, does not produce ions so it does not conduct electricity.3. Dilution of concentrated acid is an exothermic process. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. On the other hand, adding acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize it. thank |
