Examples of commonly encountered acids are hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (C2H4O2), and some common bases are sodium hydroxide (NaOH) and potassium hydroxide (KOH). Acids and bases react with each other, and when they do so the resulting products are water (H2O) and an ionic compound, i.e., a "salt".

In equation 1, the acid is HCl (called hydrochloric acid) and the base is NaOH (called sodium hydroxide). When the acid and base react, they form NaCl (sodium chloride), which is also known as table salt. The titration proceeds until the equivalence point is reached, where the number of moles of acid is equal to the number of moles of base.

In 1.00 L of solution, we have 263 g citric acid and (1.10 × 103 ( 263) = 840 g of H2O. molality = = 1.6 mol/kg. 840 g H2O × = 47 mol H2O; = 0.028. Since citric acid is a triprotic acid, the number of protons citric acid can provide is three times the molarity. Therefore, normality = 3 × molarity: normality = 3 × 1.37 …

Using concentrated hydrochloric acid, Mary prepared a solution of 100 mL to be 1.00 mol/L. However, when she titrated it against a primary standard of 1.00 mol/L sodium hydroxide, she needed 10.35 mL of NaOH to neutralize 10.00 mL of her HCl. How much water should she add to the remaining 90 mL of acid to make it exactly 1.00 mol/L?

Note that since Z is generally equal to or greater than unity, the normality of a solution will be equal to or greater than its molarity. Normality = Molarity * Z (2.10) For acids, Z is simply the number of protons that will be donated. Z = 1, for monoprotic acids (e.g., hydrochloric acid or acetic acid) HCl -----> H+ + Cl- …
