A solution with pH of 9 is?
A solution with a pH of 9 is considered to be alkaline or basic. This means that it has a low concentration of hydrogen ions and a high concentration of hydroxide ions. Examples of substances with a pH of 9 include baking soda solution and seawater.
How many more hydroxide ions are there in a solution with a pH of 9 than in a solution with a pH of 3?
The concentration of hydroxide ion is realted to pH by the pKw (10-14) At pH 9 the concentration of OH- is 10-5, at pH 3, 10-11. The ratio is 106 so there are a million times as many OH- in pH 9.
What is pH of aqueous solution that contain 3.98 X10-9M in hydronium ions?
The pH of a solution can be calculated using the formula pH = -log[H3O+]. Plugging in the concentration of hydronium ions given (3.98 x 10^-9 M) into the formula will give you the pH of the solution.
Would you expect the pH of a solution of soap to be 4 or 9?
9
How does pH value of solution help to predict nature of solution?
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
