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+]

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.
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.
Ksol = [Ag+]2*[CO32-] at equilibrium (saturated solution)in which:Ksol is the thermodynamic equilibrium constant, onlydependent on temperature.[X] is the concentration of substance X in mole/Litre.Note that:the exponent 'p' in the expression [X]p is equal to the number of ions in the balanced equilibrium equation: 2Ag+ + CO32- (Ag2CO3)s. So p=2 for [Ag+]concentration of only solved particles are in the Eq. expression [Ag+]2*[CO32-] and not those of solid (Ag2CO3)s. However, some solid (Ag2CO3)s is needed to get to an equilibrium state, so at least the solution is to be saturated.

The definitive answer is 'pH = -log(10) [H^(+)] In words, ' pH is the negative logarithm, to the base ten, of the hydrogen ion concentration. As an example If H^(+) is 0.002 Then pH = -log(10)[0.002] On the calculator using the 'log' button pH = -(-2.69897...) pH = 2.69897... pH = 2.70 NB This would be an acidic pH NNB pH is always quoted to 2 d.p. only. NNNB Do NOT use the 'ln' button on a calculator.
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)

The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
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.

Concentration of hydrogen ions in the solution
A measure of the concentration of hydrogen ions in solutions is the pH. Solutions with more hydrogen ions are acids, and substances with less hydrogen ions are bases. Furthermore, each number descending has ten times the amount of hydrogen ions of the previous number (ie a solution with a pH of 5 has 1,000 more hydrogen ions than a solution with a pH of 8).
An acid increase the hydrogen ion concentration in a solution.
Adding water dilutes the solution and therefore reduces the concentration of hydrogen ions.
Acid solutions contain higher concentrations of hydrogen ions (hydronium ions).
