Standard Solutions

IQ3: How are chemicals in solutions measured?

Students:

● conduct practical investigations to determine the concentrations of solutions and investigate the different ways in which concentrations are measured (ACSCH046, ACSCH063)

● manipulate variables and solve problems to calculate concentration, mass or volume using:

– 𝑐=𝑛𝑉 (molarity formula) (ACSCH063)

– dilutions (number of moles before dilution = number of moles of sample after dilution)

● conduct an investigation to make a standard solution and perform a dilution
