What happens to the hydroxide ion concentration in water when a base is added?
When a base is added to water, the hydroxide ion concentration increases as the base donates hydroxide ions to the water. This leads to an increase in the overall alkalinity of the solution.
What happens to the hydroxide ion concentration in aqueous solutions when you increase the hydrogen ion concentration by adding an acid?
The hydroxide ion concentration would decrease in response to the increase in hydrogen ion concentration. This is due to the neutralization reaction that occurs between the added acid (which releases H+ ions) and the hydroxide ions (OH-) present in the solution.
What happens when a strong base is added to water?
When a strong base is added to water, it ionizes to release hydroxide ions (OH-) which then react with water molecules to increase the concentration of hydroxide ions in the solution. This leads to an increase in pH, making the solution more basic.
What happens when you add base to water?
When a base is mixed into water, the pH of the water increases. The pH measures the hydrogen activity in the water. During the self-ionization of water, an H2O molecule loses one of its hydrogen nuclei (deprotonization), and becomes a hydroxide ion, or OH-. The free hydrogen nucleus immediately protonates another water molecule, which becomes hydronium, or H3O+. The balance between hydroxide and hydronium is what pH measures. When the pH increases (making the water more basic), there is an increase in hydroxide, and a decrease in hydronium. When the pH decreases (making the water more acidic), there is a decrease in hydroxide and an increase in hydronium. Bases affect this process by accepting protons or donating hydroxide ions. When the bases accept hydrogen protons, this lowers the amount of hydronium in the water, thus affecting the pH. Adding hydroxide ions also affects the pH. Acids do the opposite, they can donate protons or accept hydroxide ions.
What happens when you mix a strong alkali with water?
When a strong alkali is mixed with water, it will dissociate into ions, resulting in the formation of hydroxide ions. This process releases heat, known as heat of neutralization. Additionally, the pH of the solution will increase due to the high concentration of hydroxide ions.

What happens to concentration of the hydronium ions as the pH decreases?
The concentration of hydronium ions (H3O+) increases as the pH decreases. This is because pH is a measure of the concentration of hydronium ions in a solution. As the pH decreases, the solution becomes more acidic, leading to an increase in hydronium ion concentration.
What happens when you add a base and water?
I think that the amount of hydronium ions goes down and the number of hydroxide ions goes up.
What happens when pH is lowered?
The amount of hydronium ions increase and the solution becomes more acidic.
Why water is netural in pH scale?
pH is the negative logarithm of the molar concentration of dissolved hydronium ions. a low pH indicates a high concentration of hydronium ions, while a high pH indicates a low concentration. water happens to be very close to 7.0 so it is considered neutral
When a n acid dissolves in water what happens?
When an acid dissolves in water, it ionizes, meaning it breaks apart into ions. The hydrogen ions (H+) from the acid combine with water molecules to form hydronium ions (H3O+). This results in an increase in the concentration of hydronium ions in the solution, making it acidic.

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 happens to the concentration of hydrogen ions when an acid and a base are reacted?
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
