Question

give reasons.......​

Answer 1

Answer:

1. Curd and sour substance contains aids. Acids react with metal to produce salt and hydrogen gas. So, if such substance are kept in copper container, the acid will react and the container will be corroded
2. A neutralisation reaction is referred to as a chemical reaction wherein a base and an acid quantitatively react together to form water  and a salt as products. In a neutralisation reaction, there is a combination of OH–ions and H+ions which form water. A neutralisation reaction is usually an acid-based neutralisation reaction  

Examples :-

1. The majority of the waste generated in the form of chemical effluents is harmful to our environment. But before they can be disposed off  we have to neutralize their toxicity. Specific chemicals are used on the basis of the application. Examples, sodium bicarbonate, calcium oxide, carbonate, and magnesium hydroxide are popular chemicals
2. The food must be neutralized as it passes between our stomach and intestines. However, an alkaline environment is required to absorb nutrients through the intestinal walls. This favored condition is created from the production of antacid bicarbonate

Hope this answer helped you out

Answer 2

Answer:

A. ans. Because, citrus fruits and curd contains acid inside them, and they will react with copper or brass vessels to form metal salt. which is not good for our health.

Hence, it is said that acidic food should not stored in metal vessels..

B ans... The reaction between acid and base to form salt and water is called neutralization reaction..

for ex. HCl+ NaOH ——> Nacl + H2O
