Chapter 3 17 < strong >ACID-BASEstrong > < strong >TITRATIONSstrong > The reaction of < strong >acidstrong > and < strong >basestrong > involves transfer of a proton from < strong >acidstrong > to < strong >basestrong > and is often called a neutralisation reaction. It is important to note that only a few reactions produce a neutral solution due to hydrolysis in the resultant solution. Common titrants A major requirement of an acidic or basic titrant is that the species is a strong < strong >acidstrong > or < strong >basestrong > . If a weak < strong >acidstrong > or < strong >basestrong > were used to titrate a weak < strong >basestrong > or weak < strong >acidstrong > then the equivalence point could not be detected. A strong < strong >acidstrong > or < strong >basestrong > enhances the equivalence point making it easier to detect. Common < strong >acidstrong > titrants include: Hydrochloric < strong >acidstrong > Nitric < strong >acidstrong > Sulfuric < strong >acidstrong > Common < strong >basestrong > titrants include: Sodium hydroxide Potassium hydroxide Primary standards for standardisation of an < strong >acidstrong > Sodium carbonate (anhydrous), Na2CO3.

Chapter 3 22 Strong Base vs Weak Acid The equivalence point for this reaction is greater than 7 and the indicator must change colour in the alkaline region.
