Can we store food items in a copper container? Explain in detail with the help of a chemical word equation.
Answers
Answer:
Both the Curd and sour substances are acids. Acids react with metals to produce salt and hydrogen gas. So, if such substances are kept in a copper container, the acid will react and the container will be corroded. Thereby may spoil the food.
Metal + Acid → Salt + Hydrogen
Lactic acid is an organic acid that contains -COOOH group. Hence, it is a weak acid due to the presence of this group. Lactic acid develops in cow milk because of the breaking down of bacteria. Fresh milk does not contain lactic acid. Dairy products such as yogurt, cheese and condensed milk contain high levels of lactic acid. The sour taste of substances is because they contain acid such as vinegar contains acetic acid, tamarind and grapes contain tartaric acid, lemons and oranges contain citric acid
