if the pH is 4.7, the H+ concentration is 2 x 10-5
pH is equivalent to -log[H+], therefore at a pH of 10.6, [H+] = 10-10.6
[H+] = antilog(-pH) = 3.72 = 10-pH = 10-4.43 = 0.000,037 = 3.72*10-5
3.16 * 10^-3
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
The pH is 6,15.
10 times.
The pH scale is logarithmic, with lower numbers being more acidic. So the difference between the two is 9-2 = 7. The pH 2 is 10^7 (10 million) times more acidic. Actually the pH number which is between 7 & 14 is considered alkaline or basic.
10
It has 10 times as many. pH is roughly the same as "log [H3O+]". This means "10 to what power is equal to the concentration of H3O+ ions?" So, if you go from pH 5 to pH 4, you've got a concentration of ten times fewer H3O+ ions, and ten times more H+ ions.
pH=10, means the concentration of OH- ions is 0.0001 M and concentration of H+ ions is 0.0000000001M
A change in pH of 1 unit is equivalent to a 10 fold change in the concentration of H+ ions. So, a 10 fold increase in H+ ions will lower the pH by 1 pH unit.
3.16 * 10^-3
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
The pH is 6,15.
The new pH would be 5.5. pH = -log(H+) therefore 10 to the power of -5.5 = concentration of H3O+ ions. 10 to the power of -5.5 = 3.16x10 to the power of -8. multiplied by 100 = 3.16x10 to the power of -6. -log(3.16x10 to the power of -6) = 5.5
When the pH drops from 7 to 5 the H plus concentration increases by 100 times. ie:for every drop back of pH by 1 unit the H plus concentration increases by 10 times.
8.0*10^-10 m
When pH value is decreased 1.0 unit, the H+ concentration is tenfolded, because -log(10.[H+]) = pH + 1.0
[h+]=1 * 10-2[h+][oh-]=1 * 10-14[oh-]=1 * 10-12
