- pH is defined as the negative log of the hydrogen ion concentration. A pH of 2 is 10 times stronger than a pH of 3. A pH of 2 is 100 times stronger than a pH of 4.
- The easiest way of comparing pH of 3 and 5.5 might be to convert the numbers back to hydrogen ion concentrations, [H+].
pH 3 means [H+] = 10-3 which is equal to 0.001 M
pH 5.5 means [H+] = 0.00000316 M
This means that pH 3 is 316 times stronger than pH 5.5

Is a pH of 2 stronger or weaker than a pH of 3?
Stronger
How many times a solution of pH equals 3 be diluted to get a solution of pH equals 6?
The solution must be diluted 1000 times to get from a pH of 3 to a pH of 6.
Which has stronger acid a pH of 1.2 or a pH of 3?
PH 1.2, as PH 1 is very acidic
How many times more acidic is a solution of pH 1 than a solution of pH 3?
100 times
How many times more hydroxide ions are there in a solution with a pH of 9 than a solution with a pH of 3?

How many times more hydroxide ions are there in a solution with a pH than in a solution with a pH of 3?
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.

How many times is more acidic a solution with pH 1 than with pH 3?
1 is most acidic 3 is to less than that 7 is netrul
How many times more hydroxide ions there with a pH of 9 than in a solution with a pH of 3?
