Question

If the H30+ ion concentration is increased in a solution, will the
on on (H
pH increase or decrease ? What are the probable colours of pH
paper if the pH range is 0.5 to 2.0?​

Answer 1

Answer:

If H3O+ ion concentration increases then the ph deacreases.

The probable colour is Red.

Answer 2

Answer:

The hydrogen ion concentration is increased by 10 times.

Thus ratio of hydrogen ion concentration is

=10.

Change in pH is ΔpH=pH

Thus pH will decrease by 1.
