The pH of a solution with H plus 2.3 10 -3 is 4.64.
Remember
pH = -log(10) [H^+]
In words, 'pH is the negative logarithm to the base ten of the hydrogen ion concentration.
So with a hydrogen ion concentration of 2.3 x 10^-3
We have
pH = -log(10) [2.3 x 10^-3]
One the calculator (using 'log' , NOT ln).
pH = -(-2.6382...)
Note the double negative, which now becomes positive
pH = 2.6382...
pH are quoted to 2 decimal places only, hence
pH = 2.64 The answer ....
1000 times increased. 106-3 = 103 =1000 because the pH scale is logarithmic.
the pH has 1 ions because the amoont of pH produce is the among you get.

It will increase the pH
1000 times increased. 106-3 = 103 =1000 because the pH scale is logarithmic.
the pH has 1 ions because the amoont of pH produce is the among you get.
I do not understand what you are asking? Can you rephrase your question, please?
If you think to pH it is 7.
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.

In a neutral solution, the H plus is equal to OH-. The pH level in such a solution is usually at 7.
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
