calculate the pH of 0.03 m HCL
Answers
Answer:
pH = - log [H+]
Where [H+] is the concentration of hydrogen ions/ protons present in the solution
As HCl only contains one hydrogen ion per molecule then the concentation of [H+] is 0.03 M
Then the equation can be calculated (the minus sign is very important!)
pH = - log 0.03
pH = 1.52

Key Takeaways
pH is a measure of how acidic or basic a chemical solution is.
Normally, pH runs from 0 to 14.
A neutral pH value is 7. A value less than 7 is acidic, while a value greater than 7 is basic.
The formula for pH is pH = -log[H+]. This means pH is the negative base 10 logarithm ("log" on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer.
