b.increase
c.cannot be predicted
pls answer fast​

Answer 1

Answer:

Explanation:

An aquous solution of Na2CO3 is alkaline in nature. Therefore, its pH must always be above 7.

Na2CO3 is a salt of a weak acid (carbonic acid) and a strong base, NaOH.

Therefore, the salt undergoes hydrolysis in water to produce OH - ions :

CO3 2- + 2 H2O ---------> H2CO3 + 2 OH -

A strong solution of Na2CO3 may have a pH value of around 10, if not more.
