Reach boric acid
WebThe concentration of an acid solution can be determined by titration with a strong base. First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. WebBoric acid is a weak acid (pKa = 9.15), existing in aqueous solutions at or below pH 7 as undissociated boric acid. Above pH 10 the metaborate anion dominates the solution. 3 Sodium metaborate is much higher in solubility and alkalinity than the other borates.
