What expression is used to represent the concentration of OH- ions?

pOH is the expression used to represent the concentration of OH- ions. It is calculated as the negative logarithm of the hydroxide ion concentration in a solution.


What is the ksp expression for calcium hydroxide?

The Ksp expression for calcium hydroxide is Ksp = [Ca2+][OH-]^2, where [Ca2+] is the concentration of calcium ions and [OH-] is the concentration of hydroxide ions in the saturated solution of calcium hydroxide.


How does the concentration of H plus and OH- ions determine pH?

The concentration of H+ ions in a solution determines its acidity; the higher the concentration of H+ ions, the lower the pH. The concentration of OH- ions in a solution determines its alkalinity; the higher the concentration of OH- ions, the higher the pH. pH is a logarithmic scale that represents the concentration of H+ ions in a solution.


Which pH represents a solution with a 1000 times higher OH- than a solution with pH of 5?

A solution with a pH of 5 has an OH- concentration of 1x10^-9 mol/L. To find a solution with 1000 times higher OH- concentration, we multiply 1x10^-9 by 1000 to get 1x10^-6 mol/L. The pH of this solution with a higher OH- concentration would be 8.


What is the equation for calculating H plus s or OH?

The equation for calculating H+ concentration is pH = -log[H+], where [H+] represents the concentration of hydrogen ions. For OH- concentration, pOH = -log[OH-]. These equations are used to quantify the acidity or alkalinity of a solution.


What is the H in a 0.25M solution of NaOH (strong)what is OH-?

In a 0.25M solution of NaOH, the concentration of hydroxide ions (OH-) is also 0.25M. This is because NaOH dissociates completely in water to form Na+ and OH- ions. OH- represents the hydroxide ion in solution.


What is KB for cn- aq h2o l hcn aq oh-aq?

The Kb for CN- (aq) is the equilibrium constant for the reaction of CN- with water to form HCN (aq) and OH- (aq). It represents the strength of the base CN- in solution. It can be calculated by taking the concentration of the products (HCN and OH-) and dividing by the concentration of CN- at equilibrium.


What does the expression cinders and ashes mean?

The expression "cinders and ashes" typically refers to a situation that is bleak, hopeless, or destroyed. It represents destruction, loss, or devastation.


What happens when a base dissolve?

It increases the concentration of OH - in a solution.


What happens to the pH if the concentration of H3O and OH- are the same?

If the concentration of H3O+ and OH- ions are equal, the solution is neutral with a pH of 7. This is because in neutral water, the concentration of H3O+ ions (from dissociation of water) is equal to the concentration of OH- ions.


What happends to the OH- as the H plus increases?

The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant


Which equation best represents the dissociation of water molecules into hydrogen ions and hydroxides ions?

The equation that best represents the dissociation of water molecules into hydrogen ions (H⁺) and hydroxide ions (OH⁻) is: H2O -> H⁺ + OH⁻. This reaction is known as autoionization of water and is important in the concept of pH, where the concentration of H⁺ ions determines the acidity of a solution.
