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+]

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 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.
Write the solubility product expression for Ag2Co3?
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.
If the number of hydrogen ions being pumped into the thylakoid is rapidly decreasing what is most likely happening?
Less sunlight is being used by photosystem II
What is the Coordination number?
Coordination number of an ion is the number of oppositely charged ions present around that ion as the neighbour ions , in that ionic crystal.
Concentration of hydrogen ions in solution is called?
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)
What is the PH of a solution in which the concentration of hydroxide ions is greater than the concentration of hydrogen ions?
< 7
What the pH number of an indicator for the concentration of?
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 measurement of the concentration of hydrogen ions in a solution is called?
Potential of hydrogen or 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 are the substance that can take up or release hydrogen ions into solution as hydrogen concentration of solution changes?
A buffer.
The concentration of hydrogen ions in solution is the pH of the solution the answer has to be either true or false?
False.
What expression represents the pH of a solution?
Concentration of hydrogen ions in the solution
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.
Predict what will happen to the hydrogen ion concentration of an acidic solution if you add water to it?
Adding water dilutes the solution and therefore reduces the concentration of hydrogen ions.
What scale measures the concentration of hydrogen ions in 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).
What type of solution contains a higher hydrogen concentration?
Acid solutions contain higher concentrations of hydrogen ions (hydronium ions).
