Question

Which acid ,base and salt is present in Chalk Powder

Answer 1

Answer:

calcium carbonate is present in chalk power

Answer 2

It's a salt of a strong base Ca(OH)2 and a weak acid H2CO3. CaCO3 (calcium carbonate, a.k.a. chalk) doesn't dissolve in water, so it doesn't behave like a base. All acids stronger than H2CO3 (provide their calcium salts dissolve well in water) react with calcium carbonate, yielding CO2.
