Review Chemistry 2202 Name:
Acids: - acids are hydrogen compounds that have been dissolved in water - composed of non-metals(m) - may be solids, liquids or gases or room temperature (m) - dissolve in water to form conducting solutions (i)
*Two exceptions to naming acid rules are acids which have sulf or phosph as roots. Syllables are added to theses acid names to make them sound better. Thus,
H2SO4(aq) is sulfuric acid and H3PO4(aq) is phosphoric acid.
