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

 

Answer: 

  • Brass and copper are metals. 
  • Curd and other sour substances contain lactic acid (C 3 H 6 O 3 ). 
  • When metals react with acids , they produce salt and hydrogen gas . 
  • When sour substances like curd are kept in brass or copper vessels , the lactic acid in curd reacts with the metals which leads to the corrosion of the vessels as well as the formation of harmful salts that cannot be consumed.
