Question

in the titration of a weak acid with a strong base, the point at which the number of moles of acid equal the number of moles of base is called the

Answer 1

equivalence point. At this point, the solution is neutralized and the pH will be higher than the initial pH of the weak acid. The equivalence point can be determined by using an indicator or by monitoring the pH with a pH meter. It is important to note that the equivalence point is not necessarily equal to the pH at which the buffer capacity of the solution is highest. In fact, if the weak acid has a high Ka value, the buffer capacity will be highest at a pH close to its initial pH. Overall, understanding the equivalence point in titrations is crucial for determining the concentration of unknown solutions and for predicting chemical reactions in various applications.
