Question

why should curd and sour substances not be kept in brass and copper vessels??​

Answer 1

Fresh milk does not contain lactic acid. Hence when these acids react with metals they give salt and hydrogen. If these kinds of substances which possess acids are kept in copper containers or vessels they will react and produce salt and hydrogen and the vessel will be corroded.
