Question

An aqueous solution of metal nitrate P reacts with sodium bromide to form yellow ppt compound Q which is used in photography?

Answer 1

Answer:

The compound P is AgNO3 ( Silver Nitrate) and compound Q is AgBr ( silver bromide )

Answer 2

Answer:

P is AgNO₃ (Silver Nitrate)

Q is AgBr (Silver Bromide)

===================================================

Balanced chemical equation for Silver Bromide::

2AgBr -----> 2Ag + Br₂

                             (reddish brown)

Type of reaction :: Decomposition reaction

=======================================================
Balanced chemical equation for the reaction between Silver Nitrate and Sodium Bromide:

AgNO₃ (aq) + NaBr (aq) -----> AgBr (s) + NaNO₃ (aq)

                                             ( yellow ↓)  

Type of reaction :: Double Displacement reaction

↓ = precipitate (ppt)
