Question

1. A 0.100 m solutuon of bromoacetic acid (BrCH₂COOH)is 13.2% ionized. Calculate [H⁺],[BrCH₂COOH]and K_a for bromoacetic acid.

2. Complete and balance the following equations, and identiy theoxidizing and reducing agents. (Recall that the O atoms in hydrogenperoxide, H₂O₂ have an atypical oxidationstate.)

a) NO₂^-(aq) +Cr₂O₇^2-(aq) -->Cr³⁺(aq) + NO₃^-(aq) (acidicsolution

b) S(s) + HNO₃(aq) -->H₂SO₃(aq) + N₂O(g) (acidicsolution)

c)Cr₂O₇^2-(aq) +CH₃OH (aq) --> HCO₂H (aq) +Cr³⁺(aq) = acidic solution)

d) BrO₃^-(aq)+N₂H₄(g) --> Br^- (aq0 +N₂ (g) (acidic solution)

e) NO₂^-(aq) + Al(s) -->NH₄⁺(aq) + AlO₂^-(aq)(basic solution)

f) H₂O₂(aq) + ClO₂(aq)-->ClO₂^-(aq) + O₂(g) (basicsolution)
