What is the oxidation state of carbon in \(\mathrm{CaC}_2\) and \(\mathrm{K}_2 \mathrm{C}_2 \mathrm{O}_4\) respectively?
- A -2 and +6
- B -1 and +3
- C +2 and +2
- D -2 and +3
Answer & Solution
Correct Answer
(B) -1 and +3
Step-by-step Solution
Detailed explanation
\(\mathrm{CaC}_2 \)
\( +2+(x \times 2)=0 \text { or } x=-1 \)
\( \mathrm{~K}_2 \mathrm{C}_2 \mathrm{O}_4 \)
\( \therefore (+1 \times 2)+(x \times 2)+(-2 \times 4)\) \(=0 \text { or } x=+3\)
\( +2+(x \times 2)=0 \text { or } x=-1 \)
\( \mathrm{~K}_2 \mathrm{C}_2 \mathrm{O}_4 \)
\( \therefore (+1 \times 2)+(x \times 2)+(-2 \times 4)\) \(=0 \text { or } x=+3\)
