Question

When each of the following substances is mixed with water to make a homogenous solution could you identify the solution that will have a pH higher than seven? CH_3CO_2Na HClO_4 HF NH_4Cl CH_3CO_2H Assume that the equilibrium constant for the following reaction is known. 2NO_2(g) 2 NO(g)+ O_2(g) K_1 = 74 times 10^-16 (at 25 degree C) What is the correct value of the equilibrium constant for the opposite reaction? 2 NO(g) + O_2(g) 2 NO_2(g) K_2 = ? K_2 = 1.4 times 10^15 K_2 = 3.0 times 10^17 K_2 = 7.4 times 10^-15 K_2 = 1.8 times 10^-14 impossible to determine from this information What would be the effect of removing some NO_2 from the following system after the reaction reaches equilibrium at 25 degree C?

Explanation / Answer

9 ) answer A) CH3CO2Na

Because it contains acetate ion which is conjugate base of acetic acid. So acetate is base and it will have pH greater than 7.

All the remaining compounds are acids.
