Consider this reaction: koh + hbr --> kbr + h2o

which statement is most likely true about koh?

a) it turns blue litmus red.

b) it turns clear phenolphthalein pink.

c) it reacts with metals to form hydrogen gas.

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
