★ MINERAL ACIDS

• The acids prepared from the minerals of the earth are called mineral acids.

• These are man-made acids.

(Concentrated mineral acids are dangerous. They can burn our hand & clothes.

In laboratory, acids are generally mixed with water to dilute them these acids are called dilute acids.)
