Which of the following statements are correct ?A. According to Bronste

1.	Which of the following statements are correct ?A. According to Bronsted Lowry concept, `H_(2)SO_(4)` can also act as a baseB. `SiF_(4)` is an acid according to Lewis conceptC. Stronger the acid, higher is its `pK_(a)` valueD. HCl, `HNO_(3) and H_(2)SO_(4)` act as equally strong acids in any solvent.
Answer» Correct Answer - A::B (a) is correct because in presence of `HClO_(4)`,`H_(2)SO_(4)` can accept a proton and hence can act as a base. (b) Si has empty d-orbitals to accept electrons. Hence, Si`F_(4)` is a Lewis acid.
