Question

Grade 12 chem

Describe how to prepare 750.0 mL of a standard 2.00 M sulfuric acid solution. Be sure to identify any special lab equipment required. Show all calculations. (3 marks for math, 3 marks for description) 

Answer 1

Preparing a solution of known concentration is perhaps the most common activity in any analytical lab. The method for measuring out the solute and the solvent depend on the desired concentration and how exact the solution’s concentration needs to be known. Pipets and volumetric flasks are used when we need to know a solution’s exact concentration; graduated cylinders, beakers, and/or reagent bottles suffice when a concentrations need only be approximate. Two methods for preparing solutions are described in this section.
