Question
1. Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients.
A precipitate forms when aqueous solutions of magnesium iodide and lead(II) nitrate are combined.
Use the pull-down boxes to include states such as (s) or (aq).
2. Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients.
A precipitate forms when aqueous solutions of silver(I) nitrate and potassium hydroxide are combined.
Use the pull-down boxes to include states such as (s) or (aq).
3. Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients.
A precipitate forms when aqueous solutions of silver(I) nitrate and potassium carbonate are combined.
Use the pull-down boxes to include states such as (s) or (aq).
Explanation / Answer
1.Reaction between magnesium iodide(MgI2) and lead(II) nitrate(Pb(NO3)2)
MgI2 +Pb(NO3)2(aq)=Mg(NO3)2(aq) + PbI2 (double replacement reaction)
2 2AgNO3(aq)+2KOH= Ag2O (ppt)+2KNO3(aq)+2H2O
siver nitrate react with potassium hydroxide to produce oxide silver(1),potassium nitrate and water.potassium hydroxide-diluted solution as a result brown colour precipitate Ag2O is formed.
3.2AgNO3 + K2CO3 = Ag2CO3 + 2K2NO3
