Carbon dioxide was passed into a violet litmus solution. What is the color of the solution? Why does the indicator color change?

When carbon dioxide interacts with water, carbonic acid is formed. In acid solutions – red litmus (in a solution of weak carbonic acid – pink). Therefore, the color of the indicator changes from violet (in a neutral solution) to pink (in acidic),
CO2 + H2O = H2CO3
