pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
pH 6 is a very weak acid and pH 9 is an alkaline
Baking soda has a PH of 9
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
it has a ph of 9
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
pH 6 is a very weak acid and pH 9 is an alkaline
Baking soda has a PH of 9
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
This is a basic pH.
everything has a pH
it has a ph of 9
7 is neutral below 7 is acidic above 7 is basic therefore a pH of 5 is more acidic as a pH of 9
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
Calcium Carbonate has a PH of about 9-10
pH 9-10
the pH would be 7 - 9
