1. What characterizes a strong acid or base? (1 point)polar covalent bondingcomplete ionization in waterionic bonding presence of a hydroxide or hydrogen ionWhat is another name for the acid dissociation constant? (1 point)equilibrium constantionization constantrate constantmole fraction Acetic acid ionizes in water as follows: CH3COOH + H2O CH3COO– + H3O+Fewer than 1% of ethanoic acid molecules are ionized at any instant. The acetate ion (CH3COO– ) is therefore ____. (1 point)a poor hydrogen-ion acceptora good hydrogen-ion acceptora poor hydrogen-ion donora good hydrogen-ion donorA substance of Ka of 1 x 10–5 would be classified as a ____. (1 point)strong acidweak acidstrong baseweak baseA base has a Kb of 2.5 x 10–11. Which of the following statements is true? (1 point)This is a concentrated base.This base ionizes slightly in aqueous solution.This is a strong base.An aqueous solution of this base would be acidic.

1. A strong or weak base will easily separate into its ions when added to water, Therefore it will be highly soluble. "complete ionization in water"See above. " Ionization constant"Look at the reaction. The CH3COOH lost a hydrogen, and the H2) gained a hydrogen to form the hydronium ion (H3O+). Therefore, "a good hydrogen-ion donor"Take the negative log of that number....=5The pH is 5. If a pH of 7 is neutral, and less than 7 is acidic, greater than 7 is basic .... Is 5 closer to 1 or 7? Is it more acidic or closer to neutral?Same as above. Take then negative log of Kb.....= 10.6So is it closer to 7 (neutral) or closer to 14 (highly basic)?
