∙ 8y agoH2SO4 is a strong acid for the first dissociation where H2SO4 ---> H+ + HSO4-
Neglecting the second dissociation which is small compared to the first, the [H+] = 0.3 M
pH = -log [H+] = -log 0.3
pH = 0.5
NOTE: if you want to include the second dissociation, you need to look up the Ka for that, calculate the [H+] from that dissociation, add it to the 0.3 M and then find negative log of that value.

What is the pH value of maaza?
The pH is under 7.
What is the pH value for radium chloride?
it has no effect on ph. it is neutral
What is the pH of a 0.000626 M solution of H2SO4?
- log(0.000626 M H2SO4) = 3.2 pH -----------
What is the pH obtained on dissolving 0.01M of H2SO4 in 2 liters of solution?
Assuming pH on just simple concentration. - log(0.01 M H2SO4) = 2 pH =====
Calculate the PH value of 0.004 of HCL Solution?
pH or power of hydrogen is a scale which is used to measure acidity or basicity of an aqueous solution. low ph means more acidic and high ph means more alkaline. pH scale is logarithmic and is give by the formula: pH = - log (H+) ion here , H+ = 0.004M pH= - log (0.004) using log table we can find the value as pH= 2.397
Why does addition of H2SO4 stop reactions?
H2SO4 is an acid, so when you add that to the catalase reactions, the pH drops below where the catalase can function. Acids have lower pH and therefore the catalase can no longer function, so the reaction stops.
A substance with a pH of 2 is a?
The strong acids have pH=2 as HCl or H2SO4.
What is the pH value of rennie?
it has a pH value of 8.
Which acid has the pH value of 1?
AnswerpH=1 --> [HCl] = 0.10 mol/L , and this is why: By definition [H+] = 10-pH or pH = -log [H+]So at pH = 1.0 level the [H+] concentration is [H+] = 10-pH = 10-1.0 = 0.10 mol/LIf the acid is a strong, monoprotic acid like HCl and HNO3 then the acid concentration equals the [H+] = 0.10 mol/L HClIf the acid is a strong but diprotic acid like H2SO4 then the acid concentration equals half of [H+] , so acid conc. = 0.050 mol/L H2SO4
What is the pH value of lotion?
the ph value of lotion is 7
What is pH value of apple?
the pH value of apple is 3.60
What is the pH value of lemon juice?
The pH value of lemon juice is 2.about pH = 2 to 2.5
