The total acid concentration (nitric + nitrous acid) of the 10.0 mL solution of “acid rain” is determined by an acid-base titration method. You add 5.00 mL of the titrant sodium hydroxide with a concentration of 0.0114 M to reach the endpoint. .Write one net ionic equation for the acid-base reaction occurring during titration (Think in context of what chemical species in solution are reacting with each other to get a color change at endpoint) .
