Accounting & Finance; Business, Companies and Organisation, Activity; Case Studies; Economy & Economics; Marketing and Markets; People in Business Is an aqueous solution of Na2SO3 acidic, basic, or neutral? Is an aqueous solution with pOH = 2.17 acidic, basic, or neutral? Explain. Bases are the chemical opposite of acids. HBr dissociates (it is strong acid), proton protonates nitrogen, Br. Is a solution with OH- = 2.2 x 10-2 M acidic, basic, or neutral? Is an aqueous solution with OH- = 4.1 x 10-11 M acidic, basic, or neutral? [OH^-]= 7.7 x 10^-9 M is it; Determine whether a 0.0100 M NaF solution is acidic, basic, or neutral. which is what we would expect if we think about the salts that we were originally given for this problem.

(b) Assuming that you have 50.0 mL of a solution of aniline salt. {/eq}. H3PO4) its a bit more complicated and we need to use Ka and Kb to determine the pH of the resulting solution.More chemistry help at http://www.Breslyn.org. Explain. This acid-base chart includes the K a value for reference along with the chemical's formula and the acid's conjugate base. Explain. Explain. Is an aqueous solution with OH- = 1.36 x 10-9 M acidic, basic, or neutral? NH4CN - salt from a weak acid (HCN) and a weak base (NH3) - pH will depend on the Ka and Kb. Explain. Direct link to UnrealDreamer989's post So if x is not smaller th, Posted 8 years ago. The concentration of Explain. See the chloride ion as the conjugate base of HCl, which is a very strong acid.
