pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer
pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer
- log(7.08 X 10 -12) = 11.1 pH ========
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
The pH will be 7.that is, it is neutral
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 8, that means that the concentration of H+ is equal to 1*10-8 molar, because -log(1*10-8) = 8.And 1*10-8 is equal to 0.00000001, and so if the concentration of H+ is equal to 0.00000001 M, than the pH of the solution is 8 However, a solution with pH = 8 is considered BASIC, not acidic. If the pH is less than 7, it is acidic. If the pH = 7, the solution is neutral, and if the pH is greater than 7, it is considered basic.So the numbers are correct, but the solution is not called acidic.

The pH will be 7.that is, it is neutral
A pH of 1-7 means that the solution concerned is definitely acidic. There is a larger abundance of protons in these solutions than in alkaline solutions of pH 8-14. pH 7 is neutral- neither acidic or alkaline. This figure is based on the pH of water.
Solutions with a pH over 7 are basic, and the higher the number, the stronger a base they are. A solution with a pH of 8 is a base.
- log(1.0 X 10 -8 M)= 8 pH------------ log(1.0 X 10 -6 M)= 6 pH---------The pH lowered in solution 100 times in concentration of H +. From basic, 8 pH, to acidic, 6 pH.
