Answer:

pH=12.698

Step-by-step explanation:

the pH of a solution is given by the negative logarithm of the concentration of H+ ions present in the solution

pH= -log[H+]

here H+ is concentration of H+ ions in moles per litre

now

pH= -log[2.0×10^-13]

= -log2 - log10^-13

= 13-log2

=12.689

Step-by-step explanation:

The pH of a solution is defined as the negative logarithm of the concentration of H+ ions in the solution.

Using the given concentration of H+ ions, we can find the pH using the following formula:

pH = -log[H+]

where [H+] is the concentration of H+ ions in moles per liter.

Substituting the given concentration in the formula, we get:

pH = -log(2.0 × 10^-13)

Using a calculator, we can evaluate this expression to get the pH of the solution:

pH = 12.70

Therefore, the pH of the solution is 12.70. This indicates that the solution is very basic or alkaline, as pH values greater than 7 indicate basic solutions.
