This is principally caused by thermal decomposition of bi-carbonate ions but also happens to some extent even in the absence of such ions. The resulting build-up of scale can restrict water flow in ...

Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

Distillation can be used to separate and collect a liquid from a solution. Distillation can also be used to soften water as the water evaporates as it is heated and the ions are left behind.

During neutralisation the H + ion from the acid joins with the ... O\) This is true for all neutralisation reactions. \(Metal\,carbonate + acid \to salt + water + carbon\,dioxide\) \(2HCl ...

The potassium carbonate dissolves in the water, along with some other salts ... defined as a process in which atoms, molecules, or ions gain electrons.) We obtained aluminum powder by filing ...
