The conjugate acid of the dihydrogen orthosilicate anion (H2SiO42−) is:A.HSiO43−.B.H3SiO4−.C.H4SiO4.D.H3O+.
Question
The conjugate acid of the dihydrogen orthosilicate anion (H2SiO42−) is:
A. HSiO43−
B. H3SiO4−
C. H4SiO4
D. H3O+
Solution
The conjugate acid of any base is formed by adding a proton (H+) to the base. The dihydrogen orthosilicate anion (H2SiO42−) can accept a proton to form its conjugate acid.
So, if we add a proton (H+) to H2SiO42−, we get H3SiO4−.
Therefore, the conjugate acid of the dihydrogen orthosilicate anion (H2SiO42−) is H3SiO4−. So, the correct answer is B. H3SiO4−.
