Alkali salt - Wikipedia

Alkali salts or basic salts are salts that are the product of incomplete neutralization of a strong base and a weak acid.. Rather than being neutral (as some other salts), alkali salts are bases as their name suggests. What makes these compounds basic is that the conjugate base from the weak acid hydrolyzes to form a basic solution.

Alkali-Aggregate Reaction

Alkali-silica reaction (ASR) is of more concern because aggregates containing reactive silica materials are more common. In ASR, aggregates containing certain forms of silica will react with alkali hydroxide in concrete to form a gel that swells as it adsorbs water from the surrounding cement paste or the environment.

KryssTal : Acids, Bases and Salts

Bases and Alkalis. A Base is a substance that gives OH-ions when dissolved in water.. Bases are usually metal hydroxides (MOH). Examples include Sodium Hydroxide, NaOH, Calcium Hydroxide, Ca(OH) 2.The solution of a base in water is called an alkali.. The two bases above react with water in the following ways:

Body’s pH relation to Disease & Aging (Acid- Alkaline)

All kidney disease is acid related, which can be improved by an alkaline diet. Kidney stones are salts of phosphoric acid and uric acid, coined with calcium and/or magnesium. These salts are acidic salts that gradually build up into a stone-like objects Calcium and magnesium are in the salts, they are there to soften the
