Which of the following is not a chemical equation involved in the process of carbonic acid forming and dissolving calcite? Question 12 options:

CO2 + H2O → H2CO3

H2CO3 → H + HCO3

HCl + OH → H2O + Cl

CaCO3 + H → Ca + HCO3

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
