What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
What has more hydrogen ions acidic or basic solutions?
A hydrogen ion is just a proton, H+. The pH of a solution depends on proton concentration, pH = -log of H+ concentration. Therefore, the greater the number of protons present in solution, the lower the pH number, and the more acidic the solution.
What is the measure of acidity in terms of hydronium ion concentration?
pH is a measure of the activity of hydroxide (OH-) and hydronium (H3O+) in aqueous solution. Acidic solutions have greater numbers of reactive hydronium ions. Basic solutions have more hydroxide ions and less reactive hydronium ions.
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 the pH number of an indicator for the concentration of?
The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
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 has more hydrogen ions acidic or basic solutions?
A hydrogen ion is just a proton, H+. The pH of a solution depends on proton concentration, pH = -log of H+ concentration. Therefore, the greater the number of protons present in solution, the lower the pH number, and the more acidic the solution.
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 is the measure of acidity in terms of hydronium ion concentration?
pH is a measure of the activity of hydroxide (OH-) and hydronium (H3O+) in aqueous solution. Acidic solutions have greater numbers of reactive hydronium ions. Basic solutions have more hydroxide ions and less reactive hydronium ions.
What substance increases the number of OH?
A substance that increases the concentration of hydroxide ions in solution (OH-), is referred to as an Arrhenius base.
When the concentration of hydrogen ions increases the pH number of a solution does what?

An acid produces which solution?
An acid has a greater concentration of H+(hydrogen ion) and a lower concentration of OH-(hydroxide).
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?
It produces a neutral salt along with water
