$ Na_2CO_3(aq)+HCl(aq)\xrightarrow{{}} $ $ N{{a}^{+}}(aq)+C{{l}^{-}}(aq)+H_2O(l)+CO_2(g) $
Options:
A) (i) 6, (ii) 4, yes
B) (i) 6, (ii) 6, No
C) (i) 4, (ii) 4, No
D) (i) 4, (ii) 4, yes
Show Answer
Answer:
Correct Answer: C
Solution:
[c] The redox reaction involve loss or gain of electron(s) i.e. change in oxidation state. Given reaction is not a redox reaction as this reaction involves no change in oxidation state of reactant or product.
