Which substances increase the H concentration in a solution?
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.
What is a measure of the H plus concentration in a solution?
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
What effect will decreasing the H plus of a solution have on pH?
Decreasing the concentration of H+ ions will raise the pH of the solution because pH is a measure of the hydrogen ion concentration. As H+ ions decrease, the solution becomes more basic and the pH value increases.
Can the amount of a solution affect the pH of that solution?
Yes, the amount of a solution can affect the pH if the solution is a dilute acid or base. Adding more of a dilute acid will increase the concentration of H+ ions and decrease the pH, while adding more of a dilute base will increase the concentration of OH- ions and increase the pH.

H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
How does the concentration of H plus and OH- ions determine pH?
The concentration of H+ ions in a solution determines its acidity; the higher the concentration of H+ ions, the lower the pH. The concentration of OH- ions in a solution determines its alkalinity; the higher the concentration of OH- ions, the higher the pH. pH is a logarithmic scale that represents the concentration of H+ ions in a solution.

What is the pH of a solution with H plus 7.0 x 10-12?
The pH of a solution with an H+ concentration of 7.0 x 10^-12 is 11.15. This is calculated by taking the negative logarithm (to base 10) of the H+ concentration.
What does the PH solution of a acid and base depend on?
The pH of a solution containing an acid or base depends on the concentration of hydrogen ions in the solution. For acids, the higher the concentration of hydrogen ions, the lower the pH. For bases, the higher the concentration of hydroxide ions (or lower concentration of hydrogen ions), the higher the pH.
What does a base do in a solution?
A base in an aqueous solution will either accept a proton (H+), produce an OH- ion, or be an electron pair donor (Lewis base).
What effect will decreasing the H plus of a solution have on pH?
Decreasing the concentration of H+ ions will raise the pH of the solution because pH is a measure of the hydrogen ion concentration. As H+ ions decrease, the solution becomes more basic and the pH value increases.

Yes, the amount of a solution can affect the pH if the solution is a dilute acid or base. Adding more of a dilute acid will increase the concentration of H+ ions and decrease the pH, while adding more of a dilute base will increase the concentration of OH- ions and increase the pH.
Which type of chemical substance lowers the H concentration in a solution?
A base or alkaline substance lowers the H (hydrogen ion) concentration in a solution. Bases can accept or remove hydrogen ions from the solution, increasing the concentration of OH- ions and thereby reducing the concentration of H+ ions. Examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).
What is a measure of the h concentration in a solution?
The measure of the H+ concentration is the pH.
What substance decreases the H ion in a solution?
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
