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.
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======
pH = -log[H+]
The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
An acid; pH is a measure of the [H+] of a system. A solution with high [H+] is acidic, and has a low pH, according to the equation: pH = -log10([H+])
p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH
The pH is 5,6.
The pH is 3,44.
pH=6,15
The pH is 9,9.
The pH scale is a convenient method for expressing the hydronium ion concentration of a solution. pH = log(1/[H+]) = -log [H+]. [H+] is the hydronium ion concentration in M (molarity), which is the number of moles of solute per liter of solution.
pH is the negative logarithm of [H+] ion concentration in a given solution. pH = -log[H+] It is basically used to check the acidity or basicity of the solution. Lower the pH, more acidic is the solution. At room temperature pH=7 represents neutral solution and pH<7 or pH>7 represents acidic or basic solution respectively .
pH of a substance is directly related to the the amount of H+ ions it produces in the solution. It is the negative logarithm of the concentration of the H+ ions in the solution of a substance.
The pH is the negative log of [H+].
