Question

When k2so4 is added to a concentrated solution of h2so4 the acidity of solution increases or decreases?

Answer 1

Answer:

K2so4+h2so4=k2so4(4)+h2. It's acidic solution is decreases. Thank u I hope it is helpful for u.

Answer 2

The acidity of the solution decreases due to common ion effect.

• Common ion effect is the suppresion of the dissociation of an electrolyte due to the presence of a common ion in the solution.
• The dissociation of sulfuric acid is suppressed due to the presence of sulphate ions that are produced by the potassium sulfate.
• Hence, lesser protons(H+) are produced as compared to earlier condition, which in turn decreases the acidity of the solution.
