1.	Which of the following statements are correct ?
Answer» According to Bronsted Lowry CONCEPT, `H_(2)SO_(4)` can also act as a BASE `SiF_(4)` is an acid according to Lewisconcept Stronger the acid, higher is its `pK_(a)` value HCl, `HNO_(3) and H_(2)SO_(4)` act as equally strong acids in any solvent. Solution :(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.
