The provided solution addresses several questions, including writing ionic equations, predicting observations, identifying substances, and writing formation equations based on provided information abo

Here are the answers to the questions you've provided.

Some questions cannot be answered due to missing information or incomplete diagrams:

• b. Write ionic equation for the reactions colourless solution (II) with Pb(NO₃)
• c. Write observations that would be made when ammonia solution is added drop wise till in excess colourless solution(II)
• 4.ii.a. Identify substances A-, B-, F-, G-
• 4.ii.b.i. Write down the equation for the formation of Substance C
• 4.ii.b.ii. Write down the equation for the formation of E and F

These questions require definitions for "colourless solution (II)" or a complete flow chart with labeled substances
