Worked Solution & Example Answer:When lead nitrate solution and potassium chloride solution are mixed, potassium nitrate and a precipitate of lead chloride are formed - Edexcel - GCSE Chemistry Combined Science - Question 3 - 2023 - Paper 1
Step 1
Complete the word equation for this reaction.
Answer
The balanced word equation for this reaction can be completed as:
Lead Nitrate + Potassium Chloride → Potassium Nitrate + Lead Chloride
This shows the reactants (lead nitrate and potassium chloride) reacting to form the products (potassium nitrate and lead chloride).
Step 2
Which hazard symbol should be on a container of lead nitrate?
Answer
Given that lead nitrate is toxic, the appropriate hazard symbol that should be displayed on a container of lead nitrate is symbol C (the hazard symbol indicating toxicity). This symbol warns users about the toxic nature of the substance, ensuring safe handling and awareness.
