For the following reaction identify the acid and the base and predict the position of the equilibrium. 1= acid; base; 11= base; Il = acid; 11= base; favor the right side favor the right side favor the left side acid; 1= base; 11= acid; favor the left side 1= acid; 11 = base; at equilibrium so equally favors both sides ABCDE OD OE OC O

Which of the acids listed below has the weakest conjugate base? O O HBr, K₂ = 10+9 O H3PO4; K₂ = 7.520x10-3 O HNO3; Ka = 20 H2O2; Ka = 2.400x10-12

Which of the following is NOT a strong acid? O HCIO4 O H2SO4 O HNO3 O HI O HF

According to the Bronsted Lowry definition of an acid, in the reaction below, HC,H3O2 is considered an acid because-- HC2H3O2 → H* + C2H3O2 O It accepts a proton. O Increases the hydroxide ion concentration. O It donates a proton. O It increases the hydrogen ion concentration

For the following reaction at equilibrium H3PO4 + H20 → H2PO41 + H30+1 НзРОд is the It is not on the list of strong acids and so is a acid. H2O is the . It is both a very acid and a very base. H2PO41 is the . It is not on the list of strong acids and so is a base. H30+1 is the It is a acid because it is on the list of strong acids. a. acid b. base C. conjugate acid d. conjugate base e. strong f. moderately strong or weak g. weak
