WebCheck with you specification to find out exactly what you require. Acids are hydrogen ion donors. When they react, they release H + ion (s). Bases neutralise acids. They are hydrogen ion acceptors. When they react, they accept H + ions. Some bases are known as alkalis. They contain the OH - ion and are soluble in water. http://www.gcsescience.com/aa.htm contents of audit report WebA base which is water-soluble is referred to as an alkali. So, all alkalis are bases, but not all bases are alkalis. Alkalis have pH values of above 7. In basic (alkaline) conditions red litmus paper turns blue. Bases are usually oxides, hydroxides or carbonates of metals. The presence of the OH - ions is what makes the aqueous solution an alkali.

Alkalis are soluble bases. When they react with acids, a salt and water is formed. The salt formed is often as a colourless solution. Alkalis are a source of hydroxide ions (OH⁻) when in solution. a lkali + a cid → w ater + s alt.
