Question

valency of Bicarbonate ​

Answer 1

Answer:

1 is the valency of Bicarbonate

Answer 2

Answer:

Sodium bicarbonate decomposed in sodium carbonate , water and carbondioxide.

2NaHCO3 = Na2CO3 + H2O + CO2

Oxidation number of Na, C and O are +1,+4 and -2.

Now the electrical charge of sodium carbonate is

+1×2 + 4×1 +(-2×3) = 0

And oxidation number of H is +1.

Now the electrical charge of bicarbonate(HCO3) is

+1×1 + 4×1 + (-2×3)= -1.

So, the valency of bicarbonate is 1.
