What does the h stand for in pH scale?
The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.
What does the H stand for in pH the chemical measure of acidity?
hydrogen
What factor determines the pH at the equivalence point?
the concentration of hydrogen ions - H+
What does pH indicator?
p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH
What is the pH of solution with H plus 2.310?
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
By what factor does the hydroxide ion concentration change if pH solution changes from 10 to 8?
The hydroxide ion concentration increases by a factor of 100 when the pH of a solution decreases by 2 units. This is because pH is a logarithmic scale, so each unit change represents a 10-fold difference in H+ concentration, which in turn affects the concentration of OH- ions.
Write the equation for determining pH?
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
How to calculate pH of 1N HCl solution?
The pH of a 1N HCl solution can be calculated using the formula pH = -log[H+], where [H+] is the concentration of H+ ions in the solution. For a 1N solution of HCl, the concentration of H+ ions will be 1M, so the pH will be -log(1) = 0.
What is the pH if the concentration of H plus ions is 4.5 times 10 to the -8?
if the pH is 4.7, the H+ concentration is 2 x 10-5
What relationship do you find between the pH number and the power of 10 used to express the H?
pH = -log10 [H+] So 0.001M = -log10 [H+] = 3 10 times higher concentration = 0.01M so -log10 [H+] = 2 The relationship is thus for every 1 unit of pH reduction there is a tenfold increase in concentration.
What is the pH of a solution with H 2.310-6?
The pH of a solution is given by the formula pH = -log[H+]. Therefore, if the concentration of H+ ions is 2.3 x 10^-6 M, the pH of the solution would be 5.64.
Does and acid with a pH of 1 or a pH of 3 have a greater H concentration?
An acid with a pH of 1 will have a greater hydrogen ion (H+) concentration compared to an acid with a pH of 3. This is because the pH scale is logarithmic, so each decrease in pH by 1 unit represents a tenfold increase in H+ concentration.
