pH is a scale which measures the acidity or alkalinity of a solution. It ranges from a level of 1 to 14. A pH which range from 1 to 6 represents an acidic substance. At pH of 7, signifies the solution is neutral. And at a pH of 8-14 represents a basic solution. pH is expressed as the negative logarithm of the concentration of hydronium ions. To determine the factor of how the pH will change, we use the definition of the pH.

pH = -log [H+]
5.50 = -log [H+]
[H+] = 10^-5

2.00 = -log [H+]
[H+] = 10^-2

10^-5 / 10^-2 = 0.001

The rate of reaction would change by a factor of 0.001 as the pH change from 5.5 to 2.0

What is PH scale?

pH  Scale measures whether the solution is acidic or basic.It ranges from a level of 1 to 14.

If the value on PH scale lies between 1 to 6 then it represents acidic substance.

If the value of the PH scale lies between 8-14 then it is a basic solution.

If the PH value of any substance is 7 then it is termed as a neutral substance for example water.

To determine the factor of how the pH will change, we use the definition of the pH.

pH = -log [H+]

5.50 = -log [H+]

[tex](H+)=10^{-2}[/tex]

2 = -log [H+]

[tex](H+)=10^{-2}[/tex]

[tex]\dfrac{10^{-5} }{10^{-2} } =0.001[/tex]

Hence The rate of reaction would change by a factor of 0.001 as the pH change from 5.5 to 2.0
