Tri acidic base is the one which has three replaceable hydroxyl ions in an acid base reaction
Simply, triacidic base gives three hydroxyl ion to the acid involved in a reaction
Example
Fe(OH)3 Al( OH)3 etc
In general.,acidity of any base can be determined by the number of hydroxyl ions which are replaced by the base and reverse is true for determining the basicity of an acid

Sodium bicarbonate (aka sodium hydrogen carbonate) is a salt. In water, it is completely ionized, forming Na+ ions and HCO3^- ions. HCO3^- hydrolyzes (reacts with water) and … ….. HCO3^- + H2O → CO2(aq) + OH- + H2O ……….. then simplify ….. HCO3^- → CO2(aq) + OH- The OH-makes the solution basic.
A “quick and dirty” way to tell is to look at the anion and cation of the salt. …. acid + base → salt + water ……. (Arrhenius acid/base reaction) Sodium is the cation of a strong base. And HCO3^- is the anion of a weak acid. The solution is therefore, basic. If the salt was composed of the cation of a weak base and the anion of a strong acid, then the solution of the salt would be acidic. If the salt came from a strong acid and a strong base, the salt solution would be neutral.
Common strong acids: HClO4, HCl, HBr, Hi, HNO3, H2SO4 (but only for the 1st H+) Common strong bases: all group 1 hydroxides (i.e. NaOH) and Ca(OH)2, Sr(OH)2 and Ba(OH)2.
