Document Summary
An ionic compound contains a cation and anion. Acids can be recognized by the way their formulas are written with ionizable hydrogens first. If a compound is an acid it is an electrolyte. Precipitate- insoluble solid product that separates from a solution. Precipitation reaction- chemical reaction where a precipitate forms. But precipitates don"t always form (depends on the solution solubility) Compounds containing an alkali metal cation (li+, na+, K+, rb+, cs+) or the ammonium ion (nh4+) Compounds containing the nitrate ion (no3-), acetate ion (c2h3o2-), or chlorate ion (clo3-) Compounds containing chloride ion (cl-), bromide ion (br-), or iodide ion (i-) Compounds containing the carbonate ion (co3 2-), phosphate ion (po4 2-), chromate ion (cro4 2-), or sulfide ion (s2-) Spectator ions- ions that appear on both side of an equation because they don"t precipitate. Net ionic equation- shows what exactly happens when solutions are combined. Proton refers to a hydrogen atom that lost its electron (h+)
