Weak Acids & Bases: A weak acid is not completely dissociated:- HA ?? H + + A -

Weak Acids & Bases: A weak acid is not completely dissociated:- HA ?? H + + A - Similarly, weak bases: B + H 2 O ?? BH + + OH - pKa = -log 10 Ka pKb = -log 10 Kb The smaller the pKa value - the STRONGER the acid e.g.

Bronsted /Lowry Theory of Acids and Bases

Bronsted /Lowry Theory of Acids and Bases. 1923 Danish chemist Bronsted + English chemist Lowry independently proposed new definitions for an acid and a base These simply state that: A base is a proton donor An acid is a protons aceptor. Consider This.

Chapter 9 Aqueous Solutions and Chemical Equilibria

Chapter 9 Aqueous Solutions and Chemical Equilibria. Solutions of Electrolytes Electrolytes: Form ions when dissolved in water or other solvents and produce solutions that conduct electricity. Strong Electrolytes: Ionize essentially completely. Strong conductor of electricity.

Equilibria of Weak Acids and Bases

Equilibria of Weak Acids and Bases. Strong/Weak Acids. Strong HBr, HI, HCl, HNO 3 , H 2 SO 4 , HClO 4 Readily transfer H + ion to water Completely dissociated Strong electrolyte Weak HC 2 H 3 O 2 , HCN, HNO 2 , HClO, HCO 3 - Does not readily transfer H+ ion Most remains un-ionized.
