What is the concentration of H plus in 0.50 M hydroiodic (HI) acid?
Since HI is considered a strong acid, it will dissociate 100% leading to 0.50 M H+ and 0.50 M I-. So, the answer would be 0.50 M.
How do you raise the pH of nitric acid?
By diluting the concentration of nitric acid (and the concentration of H+).
If you add hydrochloric acid to water what effect would it have on the H plus concentration on the pH?
Hydrochloric acid is HCl. It is a H plus (H^+) donor, and so adding it to water will INCREASE the H^+ concentration. Increasing the H^+ concentration results in a DECREASE in pH.
If a solution has a hydrogen ion concentration of 10-5M what is its pH?
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
What does the PH solution of a acid and base depend on?
the H+ concentration and the OH- concentration

Is H a base or acid?
HI is Hydrogen iodide. When it is dissolved in water, the solution is called hydroiodic acid or hydriodic acid.

By diluting the concentration of nitric acid (and the concentration of H+).
The strength of an acid based on concentration of what ions?
Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.

What is the hydrogen-ion concentration if the acid dissociation constant is 0.000 001 and the acid concentration is 0.01 M?
The concentration in such case is calculated including the H ion concentration contributede by water, So the [H] is .00000001+.0000001
Does and acid with a pH of 1 or a pH of 3 have a greater H concentration?
A pH of 1 has a higher H+ concentration
What is a characteristic of weak acid?
A weak acid is not fully dissociated. You need to use the Ka to calculate the concentration of H+ for a specified concentration of the acid.

What is the concentration of undissociated acid if the hydrogen-ion concentration is 0.0001 M and the acid dissociation constant is 0.0000001?
The equation is acid + water equalizes into hydronium and conjugate base, and Ka (acid dissociation constant) is products divided by reactants. If the Acid = (H+)(base)/Ka, then the acid concentration is (H+)(H+)/Ka, or (0.0001)(0.0001)/0.0000001, which equals 1M.
