pH is a measure of the concentration of the hydronium ions present in the solution. To solve for the pH of a particular solution, we can use:

`pH = -log[Acid] = -log[H^+]`

`pH = -log (1.0x10^(-4)) = 4`

If the...

The solution is acidic. 

Reason pH is less than 7.

The ionic product of a solution = [H+] X [OH-] = 1 x 10^-14

                                            => 1 x 10^-4 X [OH-] = 1 x 10^-14   

                                            => [OH-] = 1 x 10^-10

 pH of a solution is the negative reciprocal to the base ten of hydronium ion concentration

Given [H+] = 1 x 10^-4

pH is defined as -log [H+]

hence pH of solution = -log ( 10^-4)

                             = -(-4) log (10)

                             = 4

given [H+] = 10^-4` `

pH is defined as -log [H+]

hence pH of solution = -log ( 10^-4)

                             = -(-4) log (10)

                             = 4

solution is acidic , any aqueos solution whose pH < 7  is always acidic

in aqueos solutions  [H+]=[OH-] = 10^-14

hence [OH-] =(10 ^-14)/10^-4 

           [OH-] = 10^-10 .
