How the chemical balance is used
In a chemistry practical the chemical balance is used to weigh out salts for solutions, to find the mass of a crucible before and after heating, and to record the mass of a product for a percentage yield. Its 0.5 mg sensitivity sits between a student physical balance and a full analytical balance, which suits senior school and undergraduate work.
The rider scale on the beam replaces the smallest weights. A 10 mg rider is placed on the graduated beam and slid along it; because its turning effect depends on its distance from the centre knife edge, its position on the scale reads directly as a fraction of 10 mg. This avoids handling tiny fractional weights and speeds up the last stage of each weighing.
- Place the balance on a firm bench and set the zero with the balancing nuts.
- Put the container or sample on the left pan with the beam at rest.
- Add weights to the right pan down to the smallest piece needed.
- Move the 10 mg rider along the engraved scale until the pointer swings evenly.
- Read the total from the weights on the pan plus the rider position.
