The mass percent of carbon in pure sucrose, C12H22O11, is 42%. A chemist analyses an impure sample of sucrose and determined that the mass percent is 45%. Which of the following impurities could account for the high mass % of carbon in the sample?

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.
