Answer:- A. and
Explanations:- In general,
In acid-base reaction the acid gives hydrogen ion and the base gives hydroxide ion and these ions combine to form water. Rest of the ions from acid and base combine to form the salt.
Nitric acid breaks to give hydrogen ion and nitrate ion. Similarly, NaOH breaks to give sodium ion and hydroxide ion. Since, hydrogen ion and hydroxide ions form water, the sodium ion and nitrate ion forms the salt, sodium nitrate.
The reaction is shown as:
So, the right choice is A.
Answer:
D - Silver has lower reactivity than hydrogen and cannot replace it
Explanation:
If we assume , Ag also reacts just like other metals as
Metal + H₂O ---> Metal Hydroxide + H₂
then Ag forms as
Ag + H2O ----->AgOH + H2
here Ag is converting into Ag⁺ and 2H⁺ are converting into H₂
for reaction Ag --->Ag⁺ + e⁻ E° = -0.799 V
for reaction H⁺ + e⁻ ---->H₂ E° = 0 V
by Adding those 2 above equations net E° will be -0.799 which is negative.As per Faradays Law
ΔG° = -nFE°
here we got E° as negative then ΔG° will be positive
As per thermodynamics if ΔG° is +ve then reaction is not feasible
so, then given reaction does not occur.....
