H + concentration, Molarity, = 2.3 X 10 -6 M. You need to be clear in science as not everyone will figure out what you mean.
- log(2.3 X 10 -6 M)
= 5.6 pH

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 H 7.0 10 12?
11.15
What is the pH of a solution with [H+] = 7.0 x 10-2?
1.15
What is the Logarithmic formula that gives the pH of a substance?
it is equal to the negative log of H+ ions. Ph=-log[H+]
What does a pH scale look like?
Chemists devised a measurement system called the pH scale to indicate the concentration of hypotonic ions in solution. Therefore the higher the pH scale gets the more persistant it is.
If a solution of pH 6 was made into a solution of pH 3 the concentration of hydrogen ions would need to be?
1000 times increased. 106-3 = 103 =1000 because the pH scale is logarithmic.
What is the pH of a weak acid solution that has an H of 2.1 106 M?
pH = -log[H] = - log [2.1*10exp(-6)] = 5.68
What is an example of the pH of a solution that has a concentration of hydrochloric acid equal to 0.001M?
Its pH is 3
What does it mean to have the pH of a solution equal to zero?
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 0, that means that the concentration of H+ is equal to 1 molar, because -log(1) = 0. If you have a 1 M solution of any strong acid, the pH will be equal to zero.
Does the pH of a neutral solution at room temperature equal the pOH of the solution?
yes. because the ph of a neutrasl solution is 7. Meaning, the pOH of the solution is 7 7=7
How many times more hydroxide ions are there in a solution with a pH 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 the solution containing equal numbers of hydrogen and hydroxide?
It is a neutral solution, pH = 7.0 at room temp.

Is it possible to have an acid solution having strength 0.00000001 M hydrogen ions with a pH of 8?
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 8, that means that the concentration of H+ is equal to 1*10-8 molar, because -log(1*10-8) = 8.And 1*10-8 is equal to 0.00000001, and so if the concentration of H+ is equal to 0.00000001 M, than the pH of the solution is 8 However, a solution with pH = 8 is considered BASIC, not acidic. If the pH is less than 7, it is acidic. If the pH = 7, the solution is neutral, and if the pH is greater than 7, it is considered basic.So the numbers are correct, but the solution is not called acidic.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
1
What formula can you use to calculate the H3O plus?
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
