Question

If the pH values of solutions x, y and z are 13, 6 and 2 respectively then
a) Which solution is a strong acid? Why?

b) Which solution contains ions along with molecules of solution?
c) Which solution is a strong base? Why?

d) Does the pH value of a solution increase or decrease when a base is added to it? Why?​

Answer 1

Answer:

a) z is a strong acid because it has more number of H+

ions in it

c) x is a strong base because it has more number of OH- ions in it

d) increases because as the ph value increases the OH- ions increases
