To tell if KCl forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed KCl. 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.
