Question

what is the nature of CaCO3 salt and what will happen if acid with pH=6.5 is added to CaCo3?​

Answer 1

Answer:

calcium carbonate has a pH greater then 7,it's considered a base.

If we add mild acid in mild base then compound became neutral. if acid with pH=6.5 is added to CaCo3 then the compound became neutral

Answer 2

Calcium carbonate is basic in nature.It becomes neutral when an acid of $pH=6.5$ is added to calcium carbonate.

Explanation:

• Calcium carbonate is marble.
• Calcium carbonate is a salt of weak acid and a strong base.
• This means calcium carbonate can be formed when calcium hydroxide and carbonic acid reacts together.

• It is a basic salt and has a $pH=7$

• So when it reacts with a weak acid of $pH=6.5$,a salt will be forrmed along with carbondioxide and water.
• The salt formed will be relatively weak in nature.
