Question

Short answer

The negative logarithm${\mathbf{\text{H}}}^{\mathbf{\text{+}}}$ion concentration is used to calculate pH. It's a scale that's used to measure acids and bases.

${\text{pH = - log [H}}_3{\text{O}}^{\text{+}}\text{]}$

Also, we know that $\text{pH + pOH = 14}$

Step-by-step solution

Step-by-Step Solution Step 1: Understanding the concept of pH of an acid-base.

The negative logarithm${\mathbf{\text{H}}}^{\mathbf{\text{+}}}$ion concentration is used to calculate pH. It's a scale that's used to measure acids and bases.

${\text{pH = - log [H}}_3{\text{O}}^{\text{+}}\text{]}$

Also, we know that $\text{pH + pOH = 14}$

Applying the concept and calculation of concentration of hydronium ion.

Applying the concept and calculation of concentration of hydroxide ion.

The given value of pH is 8.

Now to calculate the range of concentration of ion, first, calculate the concentration at the pH= 8.
