What is the pH of a solution with [H+] = 7.0 x 10-2?
1.15
How to measure the acidity and basicity of a substances?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for power of hydrogen and numerical value for pH is just the negative of the power of 10 of the molar concentration of H+ ions.
What is the pH of a solution with H3O plus equals 1 x 10-9M?
pH = -log(hydronium concentration) [Hydronium is H3O.-log(1 x 10-9) = 9
What is more acidic 3 or 6?
A solution with a pH of 3 is more acidic than a solution with a pH of 6. The pH scale measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity. Each unit change in pH represents a tenfold difference in hydrogen ion concentration, so a solution with a pH of 3 has 1000 times more hydrogen ions than a solution with a pH of 6.
If the pH value of a solution is 4.3 what is the concentration of hydrogen ions?
The solution to this problem is simple if you just work backwards. pH= -log10[H+] You already know what your pH is, so write your equation like this: 4.3= -log10[H+] An understanding of basic logarithm properties lets you know that you can rewrite the equation like this: 10-4.3= [H+] 5.0 *10-5 = [H+]
