What would you predict about a chemical that has a hydrogen ion concentration of 1×10 to the -12 power m

You can predict its acidity (pH).

The formula for pH is: pH = log { 1 / [H+] } = log { 1 / (1*10^-12) }

=> pH = log {10^12} = 12.

Remember that acids have pH between 1 and less than 7 and basic compounds have pH greater than 7 and less than 14.

So, you can predict that this product is a base (alkaline).
