what is the pH of Sulphuric acid?
It depends upon the molarity.
pH = -log(H+)
-log = ?
pH = -log(H^+)
find (H^+), punch that into your calculator, change the sign to minus, then find the "log" key and punch that. That will be the pH.
To find the pH of sulfuric acid, we first need to know the concentration of the acid, as the pH of an acidic solution depends on the concentration of hydrogen ions (H+).
Sulfuric acid, H2SO4, is a strong acid that can ionize completely in water. It dissociates into two hydrogen ions (H+) and one sulfate ion (SO4^2-).
The pH scale is a logarithmic scale that measures the concentration of hydrogen ions in a solution. The formula to calculate pH is pH = -log[H+]. This means we need to take the negative log of the hydrogen ion concentration.
If we know the concentration of sulfuric acid, we can calculate the concentration of hydrogen ions using the balanced chemical equation and the stoichiometry.
For example, if we have a 1 Molar (1M) sulfuric acid solution, it means that every mole of sulfuric acid produces two moles of hydrogen ions. So, the hydrogen ion concentration in a 1M sulfuric acid solution is also 1M.
Using the equation pH = -log[H+], we can plug in the concentration value of hydrogen ions. In this case, for a 1M sulfuric acid solution, pH = -log(1) = 0.
Therefore, the pH of a 1M sulfuric acid solution is 0.
