The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. a basic solution has a ph of 11.2. an acidic solution has a ph of 2.4. what is the approximate difference in the concentration of hydrogen ions between the two solutions? a) 1.6*10^-9 b) 4.0*10^-3 c)6.7*10^-1 d)1.6*10^-11

Explanation:-

pH  is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

1. For a basic solution with pH= 11.2

2. For an acidic solution with pH= 2.4

As is very less as comapred to

Thus difference is

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
