O ACIDS AND BASES Identifying the major species in weak acid or weak base... The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. 0.3 mol of NaOH is added to 1.0 L of a 0.2M HCN solution. 0.3 mol of NaOH is added to 1.0 L of a solution that is 0.8M in both HCN and NaCN. acids: 0 Obases: O Oother: O O acids: 0 bases: Oother: O 0 'x 2/5 0.0. 5 Lara d F

ACIDS AND BASES: PROTON DONORS AND ACCEPTORS Bronsted-Lowry Theory is also called Proton Theory" of acids and bases. This theory was introduced independently in 1923 by the Danish chemist Johannes Nicolaus Bronsted and the English chemist Thomas Martin Lowry. Bronsted-Lowry Theory states that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base. In other words, it is based on the compounds abilities to either donate or accept protons. A Bronsted-Lowry acid is proton (hydrogen-ion) donor and a Bronsted-Lowry base is a proton (hydrogen ion) acceptor. A strong acid dissociates almost completely into a proton and a weak conjugate base, while a strong base ionizes entirely, releasing OH- ion, which is a powerful proton acceptor. Expound these: "Many biological molecules are weak acids or weak bases." "The stronger the acid, the weaker its conjugate base."
