Use this acids and bases chart to find the relative strength of the most common acids and bases. Is an aqueous solution with OH- = 0.0000015 M acidic, basic, or neutral? We have all these Explain. What is the pH of .15 M methylammonium bromide, CH3NH3Br (Kb of CH3NH2 = 4.4x10^-4), CH3NH3 (aq) + H2O (l) <=> CH3NH2 (aq) + H3O+ (aq), When dissolved methylammonium bromide dissociates to CH, am I able to use the same equilibrium constant for CH3NH2+ as I do with CH3NH2? pH = - log10([H+]). Explain. salt. So a zero concentration Will an aqueous solution of AgNO3 be acidic, basic, or neutral? Answer = C2H6O is Polar What is polarand non-polar? Is an aqueous solution with pOH = 2.17 acidic, basic, or neutral? Explain. Question: Is calcium oxidean ionic or covalent bond ? concentration of hydroxide ions. Explain. Relative Strength of Acids & Bases. So, the only acidic salt would be HONH3Br, so it would get a ranking of "1", Next comes the neutral salt KI, with a ranking of "2", NaNO2 would have the next lowest pH so ranking "3", NH4CN would have the highest pH with a ranking of "4", This is all based on hydrolysis of the salts.
