Notes:
1. Ensure that all particles of the tablet are dissolved – Chloride causes an extremely fine
distributed turbidity with a milky appearance.
Heavy shaking leads to bigger sized particles which can cause false readings.
2. High concentrations of electrolytes and organic compounds have different effects on the
precipitation reaction.
3. Ions which also form deposits with Silver nitrate in acidic media, such as Bromides,
Iodides and Thiocyanates, interfere with the analysis.
4. Highly alkaline water should - if necessary - be neutralised using Nitric acid before
analysis.
