which of the following is a polyprotic acid? select one: a. hno₃ b. ch₃cooh c. ca(oh)₂ d. none of the above
which of the following is a polyprotic acid? select one: a. hno₃ b. ch₃cooh c. ca(oh)₂ d. none of the above
Answer
Brief Explanations:
A polyprotic acid is an acid that can donate more than one proton ($H^+$). $HNO_3$ is a monoprotic acid as it donates only one $H^+$. $CH_3COOH$ is also a monoprotic acid. $Ca(OH)_2$ is a base, not an acid. So none of the given substances are polyprotic acids.
Answer:
d. none of the above
