Question

acidity changes after dry ice is added
what happens to the acidity of solutions a and b after
dry ice is added?
the ph of solution a decreases, and the ph of
solution b increases
the ph of solution a increases, and the ph of
solution b decreases
the ph of solution a increases, and the ph of
solution b increases
the ph of solution a decreases, and the ph of
solution b decreases

Explanation:

pH is a measure of acidity. A lower pH means more acidic. For solution A, pH goes from 11.0 to 9.0 (decreases). For solution B, pH goes from 8.5 to 5.8 (decreases).

Answer:

The pH of solution A decreases, and the pH of solution B decreases.
