Question

Which of the following equations represents the reaction between carbon dioxide and lime water?

• A. Carbon dioxide $\left(C{O}_2\right)$ + Lime water $\left[Ca\right(OH{)}_2]\to$ Calcium carbonate $\left(CaC{O}_3\right)$
• B. Carbon dioxide $\left(C{O}_2\right)$ + Lime water $\left[Ca\right(OH{)}_2]\to$ Calcium hydrogen carbonate $\left(CaHC{O}_3\right)$ + Water $\left(H_{2}O\right)$
  
• C. Carbon dioxide $(CO{2}_{)}$ + Lime water $\left[Ca\right(OH\left)2\right]\to$ Calcium carbonate $\left(CaC{O}_3\right)$ + Hydrogen $\left(H_2\right)$
• D. Carbon dioxide $\left(C{O}_2\right)$ + Lime water $\left[Ca\right(OH{)}_2]\to$ Calcium carbonate $\left(CaC{O}_3\right)$ + Water $\left(H_{2}O\right)$

Answer 1

The correct option is D Carbon dioxide $\left(C{O}_2\right)$ + Lime water $\left[Ca\right(OH{)}_2]\to$ Calcium carbonate $\left(CaC{O}_3\right)$ + Water $\left(H_{2}O\right)$

When carbon dioxide reacts with lime water, calcium carbonate and water are formed. Carbon dioxide $\left(C{O}_2\right)$ + Lime water $\left[Ca\right(OH{)}_2]\to$ Calcium carbonate $\left(CaC{O}_3\right)$ + Water $\left(H_{2}O\right)$
