Question

1. In the following reaction, indicate the Bronsted acid, Bronsted base, and conjugate acid base pairs NH3 H20 NH4 OH 2. The following reaction is allowed to reach equilibrium. 2 NO (g)+Ch () 2 NOCI (g) Analysis of the equilibrium mixture shows [NO] 0.574, [Cl2] 0.126, and [NOCI] Calculate the equilibrium constant 'K' for this reaction. 0.148 3. What is the pOH of a 0.085 M NaOH solution? 4. What is the [OH] for a solution at 25°C that has pH- 5.0? 5. What is the [H3O*1 for a solution at 25°C that has pOH = 3.4?

Answer 1

V let us consides a reaction, NH3 + H2O NH4+0+-- Bronsted Bronsted conjugate conjugate base aud ou acid base. too 21 let les consider a reaction, 2NO(g) + Cl2 (9) 2 Nocleg), K= (products) P = (NOC))?
