H+ ions increase in concentration at lower pH values. Calculate how many more H+ ions there are in a solution at a pH = 2 than i
joja [24]

The H⁺ ion concentration can be calculated from pH values using the following equation:

pH=-log[H⁺]

1.) Given pH = 2

Using the above equation, 2 = - log [H⁺]

Therefore, [H⁺] = 10⁻² mol/L

2.) Given pH = 6

Using the same equation, we have 6 = - log [H⁺]

Hence, [H⁺] = 10⁻⁶ mol/L

3.) Taking the ratio of [H⁺] for pH = 2 and pH = 6, we have

\frac{10^{-2} }{10^{-6} } = 10⁴

So, there are 10,000 times more H⁺ ions in a solution of pH = 2 than that of pH = 6.
