Set up an ICE table to determine the \(OH^-\) concentration: \[[OH-]=\frac{0.4\;mmol}{10\;mL+14\;mL}=0.17\;M\]. This neutralization calculator is a tool that helps you analyze reactions in which acids and bases are neutralized. Step-by-step explanation. The first will be the titration of an acid by a base. Solve for the moles of OH- that is added to the beaker. we see that a weak acid, \(CH_3CO_2H\), is being neutralized by a strong base, \(OH^-\). The water forms from the combination of the H+ ions from the acid and the OH- ions from the base. So the volume of 0.5-molar sulfuric acid that would completely neutralize 125 milliliters of a 0.1-molar sodium hydroxide solution is 12.5 milliliters. Neutralization relies on dissociation of an acid and a base. And if you don't know the density we might have it in our volume to mass calculator! The reaction of acid and base which produces salt and water is called a neutralization reaction. Units: Note that units are shown for convenience but do not affect the calculations. The acid-base neutralization Reaction Calculator is used for the estimation of the equivalent weight of acid or base. In a titration, an acid or a base is in a flask or a beaker.
