Question

what is the name of the acid whose formula is h₂co₃? spell out the full name of the acid. view available hint(s) submit part d what is the formula for sulfurous acid? express your answer as a chemical formula. view available hint(s) a chemical reaction does not occur for this question submit

Explanation:

Step1: Identify acid naming rules

For acids with poly - atomic anions ending in - ite, the acid name is formed by changing - ite to - ous acid. The anion of $H_2CO_2$ is formate ($HCO_2^-$), so the acid is formic acid.

Step2: Recall sulfurous acid formula

Sulfurous acid contains sulfur in the + 4 oxidation state. The anion is sulfite ($SO_3^{2 - }$), and to balance the charge, the formula of sulfurous acid is $H_2SO_3$.

Answer:

Part C: Formic acid
Part D: $H_2SO_3$
