For the acid-base reactions given, draw out thefull reaction using Lewis structures and curvedarrows to indicate how the reaction takes place.Predict whether the equilibrium positionwould lie to the right or the left. Explainyour reasoning.a. NH3 + H₂O = NH₂+ + OHb. NH2 + H2O = NH3 + -OH Here are the pKa values for Question 5. Did youget the answer correct in which direction theequilibrium lies for each reaction? Explain whyor why not.(Hint: You may want to first identify your acidand base followed by comparing the pkavalues of your acid and conjugate acid).+pKa H₂O = 15.7, NH4* = 9.8, NH3 = 33+a. NH3 + H₂O NH₂ + OHb. NH₂ + H₂O NH3 + OH

Given : pKa of H2O = 15.7 pKa of NH4+ = 9.8 pKa of NH3 = 33 Since pKa = -log Ka so higher is the…

Acids You make a solution by dissolving 0.0010 mol of HCl in enough water to make 1.0 L of solution. a Write the chemical equation for the reaction of HCl(aq) and water. b Without performing calculations, give a rough estimate of the pH of the HCl solution. Justify your answer. c Calculate the H3O+ concentration and the pH of the solution. d Is there any concentration of the base OH present in this solution of HCl(aq)? If so, where did it come from? e If you increase the OH concentration of the solution by adding NaOH, does the H3O+ concentration change? If you think it does, explain why this change occurs and whether the H3O+ concentration increases or decreases. f If you were to measure the pH of 10 drops of the original HCl solution, would you expect it to be different from the pH of the entire sample?
