A substance that releases hydrogen ions in water is a base. True or false?

Answers

Answer: FALSE

Explanation:

An acid is a substance which donates H⁺ (hydrogen) ions when are added to water or any other solution. The amount of H⁺ions liberates per acid molecule defines the acidity of the acid like weak or strong. The base is a substance which donates OH⁻ ions (hydroxide ions ) in the solution or water.

No it is false. Because any substance is base what include OH. If it releases H ion, it should be acid.

In a reverse reaction, products are formed from reactants and reactants are formed from products. When they yield the same amount, _____. chemical equilibrium is reached it is called the law of mass action activation energy is released

Answers

A reversible reaction is a chemical reaction where the reactants form products and products react together with reactants to give the reactants back. When they yield the same amount, Reversible reactions will reach a chemical equilibrium in which the concentrations of reactants and products will no longer change.

Explanation:

A reversible reaction is a reaction where the reactants form results, which react collectively to give the reactants back. A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from the reversible method in thermodynamics. Reversible reactions will relinquish an equilibrium point where the concentrations of the reactants and products will no longer break
