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 =====
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.
Which is the weaker acid HSO4 or H2O?
h2o, because h2so4 is a strong acid and h2o is actually neutral (pH of 7)

What is the Ph value for 0.005N H2SO4?
It is related to concentration, which you do not give.
Which is the weaker acid HSO4 or H2O?
h2o, because h2so4 is a strong acid and h2o is actually neutral (pH of 7)
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
Which is more acidic in HCl HNO3 H2SO4 and why?
H2SO4 is more acidic if you have equal molar quantities and the same volume for each (ie. Concentration) as it's diprotic . so for example a solution containing 1moldm-3 of H2SO4 has a [H+]of 2moldm-3 whereas HCL and HNO3 have will have a [H+] of 1moldm-3. [H+] is the concentration of hydrogen ions in a solution and [h+] is a measure of acidity as [H+]=10-ph or rearranged Ph=-log[H+]
What is the compound name for H2SO4?
Sulphuric Acid. In theory, however, in practice it is the chemical formula for manure.
What happen when water flows through rock?
•Influences pH + redox • •Limestone makes it more basic. • •Sulfur- oxidation yields H2SO4
How could you show that butanoic acid is a weak acid?
All the carboxyllic acids are weak acids. You can show it by adding it to water and measuring its pH which would be higher as compared to pH of strong acids like HCl, H2SO4 .
What has a pH of 2?
The strong acids have pH=2 as HCl or H2SO4.
