A reaction between colorless substances can produce a colored precipitate by formation of new ionic compound.
<h3>What is an ionic compound?</h3>
An ionic compound is a compound that is made up of two elements, one metal and the other non metal, which are held together by an ionic bonding.
When reaction occurs between two colourless substances, colored precipitate results by formation of new ionic compound.

The options in the question are:
a) +0.46 V
b) +0.617 V
c) +1.39 V
d) -0.46 V
e) +1.21 V
Answer:
b) +0.617 V
Explanation:
The equation shows that the anode is Sn2+/Sn4+ while the cathode is Fe3+/Fe2+.
The E° cell is obtained from E°cathode - E°Anode
E°cathode= 0.154V
E°Anode= 0.771V
E° cell= E°cathode - E°Anode= 0.771-0.154=0.617
Answer:
Answer: Reaction Rate
Explanation:
reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
