ion cocentration donot decrease with dilution. it is
the density of ions that decreases with dilution. because earlier the amt of ions that were present in an unit volume has been moved farther through dilution so at that unit volume we get concentration of ions less than previously it was, but overall the concentration of ions remain constant.

Effect on H concentration in a solution in base?
In a base, the concentration of hydrogen ions (H+) decreases as they accept protons to form hydroxide ions (OH-). This leads to an increase in the concentration of hydroxide ions, resulting in a higher pH and a more basic solution.
Why equivalent conductance increase with dilution whereas specific conductance decrease?
the specific conductance of the electrolyte falls because of the no of current carring particles i.e. ions present per centimetercube of the soltion becomes less and less on dilution how ever increase in eqi bacause it is the product of specific conductance and rthe volume v of the sol contain 1 gm of eq electrolyte or one mole of the elecrtrolute that's why .............................................
How does CO2 decrease the pH?
Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH. A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease. But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.
What will happen if a base is added to water?
When a base is added to water, it will dissociate, releasing hydroxide ions (OH-) into the solution. These hydroxide ions will react with water molecules to increase the concentration of OH- ions and decrease the concentration of H+ ions, resulting in an increase in pH.
Is the degree of ionisation affected by dilution?
The degree of ionization of an acid or base is not affected by dilution. Dilution simply increases the volume of the solution but does not change the proportion of ions present. The concentration of ions remains the same, so the degree of ionization remains constant.
What happens to the concentration of hydrogen ions in a 1 moles per liter solution of hydrochloric acid on repeated dilution?
The concentration become more and more lower.
Which ions is in greater concentration in an acidic pH?
In an acidic pH, the concentration of hydrogen ions (H+) is greater compared to other ions. This is because acidic solutions have a higher concentration of H+ ions, leading to a decrease in pH below 7.
Which substances decrease the hydrogen ion concentration in a solution?
Adding a base the hydrogen concentration decrease.
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.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
When a solution of acid is diluted in water, the concentration of hydronium ions decreases. This is because the dilution increases the volume of the solution, causing the same amount of acid to be spread out over a larger volume. As a result, the concentration of hydronium ions in the solution decreases.
How do hydroxyl ions and hydronium ions affect pH?
Hydroxyl ions (OH-) increase pH by combining with hydronium ions (H3O+) to form water molecules, reducing the concentration of hydronium ions. Hydronium ions (H3O+) decrease pH by increasing the concentration of hydrogen ions in the solution, making it more acidic.
Does acid increase the hydroxide ion concentration of water?
Yes, acid increases the concentration of H+ ions in water, leading to a decrease in the concentration of OH- ions. This shift in equilibrium ultimately lowers the hydroxide ion concentration.
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.
Does removing hydrogen increase or decrease acidity?
Removing hydrogen ions increases acidity. Acidity is measured by the concentration of hydrogen ions in a solution, so by removing hydrogen ions, the concentration of H+ increases, thus making the solution more acidic.
Effect on H concentration in a solution in base?
In a base, the concentration of hydrogen ions (H+) decreases as they accept protons to form hydroxide ions (OH-). This leads to an increase in the concentration of hydroxide ions, resulting in a higher pH and a more basic solution.
What happens to he hydrogen ion as you decrease the pH?
As you decrease the pH, the concentration of hydrogen ions (H+) increases. This increase corresponds to a higher acidity level. Hydrogen ions are released into the solution as acids dissociate.
