When a solution of a primary standard is prepared for titration, which of the following is required? A - HSC - SSCE Chemistry - Question 2 - 2022 - Paper 1

To prepare a solution of a primary standard for titration, a balance is essential. This is because a primary standard is a highly pure substance that must be accurately weighed to determine the exact amount needed for the solution. Proper weighing ensures that the concentration of the solution is known, which is critical for performing accurate titration. In contrast, while a burette is necessary for dispensing the titrant during the titration process, it is not required for the preparation of the primary standard solution itself.
