The fourth electron of Be atom will havequantum numbers as?11,2.2, 1, 1, +23. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. So, the conjugate base of 'HCN' will be stronger than the conjugate base of $\mathrm{HSO}_{4}^{-}$ Chapter 14 Aqueous Equilibria: Acids and Bases Chemistry 2012 Topics. The weaker the acid, the stronger the conjugate base. The conjugate base of HF is the fluoride ion F-A strong acid will have a weak conjugate base. When it donates a proton, a Cl – ion is produced, and so Cl – is the conjugate base. Write the conjugate acids for the following Brönsted bases: NH2 – , NH3 and HCOO– . Solution: HCl is a strong acid.

Acids with a smaller pK, HF(pKa=3.45) Conjugate base: F- (pKb=14-3.45=10.55), Register Alias and Password (Only available to students enrolled in Dr. Lavelle’s classes. A strong base will have a weak conjugate acid. Explanation:a conjugate base is simply an acid that has given up a proton. What will the conjugate bases for the following Bronsted acids: HF , H2SO4 HCO3 - and NH4 +. Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. In the case of HF (hydrofluoric acid), once it donates the H+ ion/proton, it becomes F- (fluoride ion).
