SALTS

Miscellaneous

Notes

(Richard Willis)

Salts are acids whose hydrogen has been replaced by a metal.
typical replacement yieldings
metal + acid gives salt + hydrogen
— for example, Na + HCl gives NaCl + H; or, Zn + 2HCl gives ZnCl + H2
metallic oxide + acid gives salt + water
— for example, CaO + 2HCl gives CaCl2 + H2O
base + acid gives salt + water
— for example: Ca(OH)2 + 2HCl gives CaCl2 + 2H2O
carbonate + strong acid gives salt + weak acid,
— for example: CaCO3 + 2HCl gives CaCl2 + H2CO3
common acids and their salts:
ClH gives chlorides; SO4H2 gives sulfates; NO3H gives nitrates; PO4H3 gives phosphates; CO3H2 gives carbonates; SiO3H2 gives silicates
Salts are for the most part the soluble forms of the molecular compositions of metals, and, as such, are less desirable for use in glaze and/or pigment mixes. However, they can be readily de-soluble’d by precipitation or by calcination and then used as non/water-soluble oxides. Also, salts, and soluble salts especially, are medium to strong deflocculants, and care should be taken accordingly to not overly deflocculate when adding salts in order to improve fluidity or porosity.
