Question
Which of the following methods to prepare a salt can be achieved using a burette and a pipette? A Nitric acid and calcium carbonate to prepare calcium nitrate. B Sulfuric acid and copper(II) oxide to prepare copper(II) sulfate. C Hydrochloric acid and zinc to prepare zinc chloride. D Hydrochloric acid and potassium hydroxide to prepare potassium chloride
Solution
The method that can be achieved using a burette and a pipette is D. Hydrochloric acid and potassium hydroxide to prepare potassium chloride.
This is because a burette and a pipette are typically used in a titration process, which is a method used to determine the concentration of a solution. In this case, the hydrochloric acid (an acid) and potassium hydroxide (a base) can be titrated to determine their concentrations. The reaction between them will produce a salt (potassium chloride) and water, which is a neutralization reaction.
The other options (A, B, and C) involve reactions between an acid and a non-metal or a metal carbonate, which are not typically measured using a burette and a pipette.
