When the concentration of hydrogen ions increases the pH number of a solution does what?
raises the pH Edited by Dr.J.: Are you kidding me? Raising the H3O+ concentration does NOT raise the pH, it LOWERS the pH. I can't believe that 8 people actually found this incorrect answer to be useful.
What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
What is the relationship between the concentration of a solution, expressed in molarity, and the number of moles of solute present in a given volume of solvent?
The concentration of a solution, measured in molarity, is directly proportional to the number of moles of solute dissolved in a specific volume of solvent. This means that as the molarity of a solution increases, the amount of solute present in that volume of solvent also increases.
What is the relationship between the pH and in hydrogen ion concentration?
pH = -log[H+].Hence lower the pH, higher is the concentration of H+ ions.For exampleAt pH = 1, [H+] = 0.1 MAt pH = 2, [H+] = 0.01 MAt pH = 3, [H+] = 0.001 Mand so on...
What does an increase 1 pH number represent?
A decrease in hydrogen ion concentration by factor of 10
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.
What happens to the number of hydrogen ions if a solution becomes more acidic?
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.

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 makes pH go up and down?
pH tells us the hydrogen ion (H+) ion concentration. The lower the number - the greater the number of hydrogen ions. Adding hydrogen ions decreases pH (and increases acidity) removing them (eg by adding hydroxide OH-) increases pH.
What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
What would happen to the concentration of hydrogen ions in a solution of a strong acid if an equal number of hydroxide ions were added to the solution?
The concentration of hydrogen ions would decrease because when hydroxide ions react with hydrogen ions, they form water. This reaction reduces the overall concentration of hydrogen ions in the solution.
What is a soulution that contains equal number of hydrogen and hydroxyl ions?
A solution that contains an equal number of hydrogen and hydroxyl ions is a neutral solution, like pure water. In pure water, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxyl ions (OH-), resulting in a neutral pH of 7.
What is meant by pH solution?
p means -log10 of a number, H is shorthand for hydrogen ion concentration. If hydrogen ion concentration is 10^-4 mols/litre, pH is 4
What measures the concentration of hydrogen ions in a solution?
pH Paper. Litmus paper Hydrogen ions determine how acidic a solution is, the lower the number on the pH scale, the more acidic it is. The color for litmus paper would be a red it it was 1 and blue if it was a base.
