What else can I help you with?
Is an alkaline solution an acid or base?
An alkaline solution is a base. Alkaline solutions have a pH greater than 7 and contain more hydroxide ions (OH-) than hydrogen ions (H+).
What is a solution called that has more OH-ions H plus ions?
When a solution has more hydrogen ions it will be acidic.
What is an aqueous solution that contains more hydroxide ions than?
An aqueous solution that contains more hydroxide ions than hydrogen ions is considered a basic solution with a pH greater than 7. This solution is known as an alkaline solution and has a higher concentration of hydroxide ions, making it a stronger base.
What causes the pH of a solution increase?
The pH of a solution increases when the concentration of hydroxide ions (OH-) increases, making the solution more basic or alkaline. This can occur by adding a base or by removing hydrogen ions (H+) from the solution.
What does a base produce when dissolved in water?
When bases dissolve in water, they usually form alkaline solution. An alkaline solution has a pH that is more than seven.
The terms base and alkaline refer to solutions that?
the more hydroxide ions releases, the more basic the solution becomes. and the solution has more hydroxide ions than hydrogen ions.
What happens when a base is added to water?
When a base is added to water, it reacts to form hydroxide ions (OH-) which increases the pH of the solution. This reaction can result in the solution becoming more basic or alkaline.
A solution that contains more hydroxide ions than hydrogen ions is?
Basic or alkaline or greater than pH 7
What is it called when the pH is greater than 7?
Anything with a pH greater than 7 is called a base. This is because pH measures the concentration of hydrogen ions in solution. Because a base usually has an ending of -OH (or hydroxide), there are more OH ions in solution than hydrogen ions.
What solutions have a greater number of hydroxide ions than hydrogen ions?
An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.
What happens to the concentration of hydroxide ions in an alkaline solution on repeated dilution?
When an alkaline solution is repeatedly diluted, the concentration of hydroxide ions decreases. This is because the amount of the alkaline substance is being spread out in more volume of solvent, resulting in a lower concentration of hydroxide ions in the solution.
What makes an Alkaline an Alkaline?
An alkaline substance is characterized by having a pH level higher than 7. This means it has more hydroxide ions (OH-) than hydrogen ions (H+) in solution. Alkaline substances tend to be bases that can neutralize acids.
