When a weak base is titrated with a strong acid, the pH of the solution decreases. This is because the strong acid neutralizes the weak base, leading to an increase in the concentration of H ions in the solution, which lowers the pH.
Yes, a strong base can be used as the titrant solution in a titration, typically in an acid-base titration. The strong base is gradually added from the burette to neutralize the acid in the solution being titrated. This allows for the determination of the unknown concentration or volume of the acid solution.
The pH at the equivalence point of a strong acid-strong base titration would be 7, as the solution is neutralized. In contrast, the pH at the equivalence point for a standard solution titration would depend on the nature of the reaction and the strengths of the acids and bases involved.
In conductometric titration of a strong acid with a strong base, as the base is added to the acid solution, the conductivity of the solution increases due to the formation of ions. The inflection point of the titration curve corresponds to the stoichiometric equivalence point, where all the acid has been neutralized by the base. The conductivity then remains constant beyond this point, indicating excess of the base.
The types of conductometric titrations include strong acid-strong base titrations, weak acid-strong base titrations, weak base-strong acid titrations, and precipitation titrations. Conductometric titrations measure the change in electrical conductivity of a solution as a titrant is added, allowing for the determination of the endpoint of the reaction.
a weak acid and strong base. At the equivalence point of a titration between a weak acid and a strong base, the resulting solution will have a pH greater than 7, indicating a basic solution. For the solution to be noticeably acidic at the equivalence point, it would suggest an excess of the weak acid after the reaction, which means that the acid is likely weak and not completely neutralized by the strong base.

The solution at the endpoint of an acid-base titration involving a weak acid and a strong base will be alkaline. This is because the weak acid will have been neutralized by the strong base, resulting in excess hydroxide ions in the solution causing it to be alkaline.
A buffer solution in titration helps maintain a relatively constant pH during the titration process. It is composed of a weak acid and its conjugate base (or a weak base and its conjugate acid). This helps prevent large changes in pH that could affect the accuracy of the titration.
In a conductometric titration of a strong acid with a strong base, the equivalence point is reached when all the acid has been neutralized by the base, leading to a sharp increase in conductivity. This abrupt change in conductivity is due to the formation of water, which is a good conductor of electricity. The initial conductivity is low due to the absence of ions in the strong acid solution, and it increases as ions are formed during the titration.
Temperature can affect the reaction rate of the strong acid-strong base titration. An increase in temperature can accelerate the reaction rate, leading to a faster titration process. This can be advantageous in terms of quicker analysis, but it is important to maintain a consistent temperature throughout the titration for accurate results.

The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
There are three major differences between strong acid/strong base and weak acid/strong base titrations. For weak acid/strong base titrations: 1. The weak-acid solution has a higher initial pH. 2. The pH rises more rapidly at the start, but less rapidly near the equivalence point. 3. The pH at the equivalence point does not equal 7.00. (should be >7) In an acid-base titration, there is a 1:1 acid:base stoichiometry, so the equivalence point is the point where the moles of titrant added equals the moles of substance initially in the solution being titrated. Therefor the strength of the acid or base should not have an affect on the quantity of base required, only on the pH of the equivalence point. The number of moles of titrant and solution will have an effect on the quantity of base required.
