Question

an acid can react with

a.Agcl

b.na2co3

c.pbso4

d.na2so4

Answer 1

An acid can react with Na2CO3. (option B)

- Acids mainly reacts with alkaline or basic substances to produce salt and water.

- Similarly, among the four chemical substances mentioned in the question,only the Na2CO3 or sodium carbonate is an alkaline substance which can react with an acid.

- For example, Na2CO3 can react with a strong acid H2SO4 to produce salt,water and carbon dioxide gas.

Chemical equation :

Na2CO3 + H2SO4 ---> Na2SO4 + H2O + CO2.

Answer 2

An acid can react with $\bold{\mathrm{Na}_{2} \mathrm{CO}_{3}}$.

Option: (b)

Explanation:  

• Only those salt reacts with an acid which are more reactive as compared to hydrogen. However sodium carbonate is much less reactive than hydrogen.  

• So sodium carbonate cannot displace hydrogen from the acid. So silver has no reaction with any of the mineral acids.  

• For this reason sodium carbonate is made into jewellery so that it has no reaction with any of the mineral acid that comes in contact in day to day activities.
