Titrations

A standard solution is a solution of known concentration

• Find how much solute you need using:
  • concentration x volume/dm^3 (to find moles)
  • moles x molar mass (to find grams)
• Weigh solid in a weighing boat then transfer to a beaker, rinsing the weighing boat into the beaker with distilled water
• Dissolve the solid with distilled water
• Transfer the solution from the beaker to a volumetric flask, rinsing out the beaker and the stirring rod into the flask with distilled water
• Top up the volumetric flask with distilled water, until the bottom of the meniscus is at the line (use a dropping pipette near the end
• Shake the flask to get a homogenous solution
