Brpnsted-Lowiy bases

Analyzing acid-base reactions according to the Brpnsted-Lowiy picture provides yet another benefit. Table 1.7, which lists acids according to theh strength in descending... 

For example, draw the Lewis acid-base reaction between eyelohexene and H-Cl. The Brpnsted-Lowiy acid HCI is also a Lewis acid, and cyclohexene, having a n bond, is the Lewis base. 

In 1923, the Brpnsted-Lowiy proton transfer theory was introduced byj. N. Brpnsted (1897-1947), a Danish chemist, and T. M. Lowry (1847-1936), an English chemist. This theory states that an acid is a proton donor and a base is a proton acceptor. 

When a Brpnsted-Lowiy acid donates a proton, as illustrated in the equation below, it forms the conjugate base of that acid. When a base accepts a proton, it forms the conjugate acid of that base. A conjugate acid and base are produced as products. The formulas of a conjugate acid-base pair differ by one proton (H" ). Consider what happens when HCl(g) is bubbled through water, as shown by this equation ... 

The pH of a solution with a hydrogen ion concentration of 0.003 M is between what two whole numbers (Table 15.4) Which is more acidic, tomato juice or blood (Table 15.5) Use the three acid-base theories (Arrhenius, Brpnsted-Lowiy, and Lewis) to define an acid and a base. 

In the following net ionic eqnations, identify each reactant as either a Br0nsted-Lowiy acid or a Brpnsted-Lowry base. Also identify the proton source and the proton remover.
