To calculation the equilibrium concentration the HNO. What is the pH that a buffer equipment which is 0.80 M in NO2- and also 0.40 M in HNO2? because HNO2 is a weak acid, it is in equilibrium through the ions, H+ and NO2-. Question c) If you add NaOH , this reacts with the HNO2 to produce much more NO2- and also reduce the concentration of the HNO2 in solution . The dissociates according to: HNO2 (aq) H+ (aq) + NO2- (aq) a.) Mol HNO2 in 50mL that 0.4M systems = 50/1000*0.4 = 0.02mol, mol NO2- in 50mL of 0.80M equipment = 50/1000*0.80 = 0.04 mol NO2-, Mol HCl in 2.0mL that 0.50M HCl equipment = 2/1000*0.5 = 0.001 mol HCl, friend now have actually 0.02 + 0.001 = 0.021 mol HNO2 in 52mL solution, You have actually reacted 0.001 mol NO2- , therefore you have 0.04-0.001 = 0.039 mol NO2- in 52mL solution, Molarity that HNO2 = 0.021/0.52 = 0.4038M HNO2, Molarity that NO2- = 0.039/0.052 = 0.75M NO2-. What will be the pH of the result solution as soon as 2.0 mL of 0.5 M HCl are included to 50 mL the this (from component a) buffer solution? HNO2 is Nitrous Acid, so that is a weak acid.
