HW ans: curd are not stored in brass and copper vessels as they are acidic in nature . The acid present in them may react with metal to form toxic compounds which are unfit for human consumption.

[@ahmedraiyan2010]

Curd and sour substances contain acids. Acids react with metals to produce salt and hydrogen gas So if we kept curd or sour substance which contains acid , will react and corrode the container. AMAZING , WONDERFUL , INFORMATIVE AND HELPFUL SESSION

[@rohanshah2369]

Ans: brass posses basic nature and curd possess acidic nature. They react with each other and give salts+ water That salts is kind of harmful for us that's why we did not kept them in brass containers.

[@Goyalmuskan182]

Homework ans👇😁💕 Curd is acidic in nature it has lactic acid in it so if we will keep it in copper or brass vessels it will react with the metal to form metal salt and hydrogen and even it will form toxic substances which can harm us 🤮🤢🤒 Ag ma'am rocks💕🔥 Ag ma'am rocks💕🔥

[@vareeshakhan23]

H.w ans : Because sour substances and curd contains Lactic acid which reacts with metal to give metal salt and H2 Gas ⛽ Thanks Ma'am 😀🥰 for Awesome session 👍🏻
