Question
CO2 dissolves in water to form:
Open in App
Solution
The correct option is B carbonic acid
Non metallic oxides react with water to form acid. The formed acid dissociates to give hydrogen ion H+ and anion (which is stabilized by oxygen and the electronegative non metallic element). These kind of acids are known as oxyacids as they have oxygen in them.Thus, when CO2 dissolves in water, some of it's amount react with water to form carbonic acid H2CO3.CO2+H2O→H2CO3Hence, the correct answer is option (B).
