Why is Sr(CN)2 considering basic? Which ion determines that?
Sr(CN)2 (aq)------------> Sr^2+ (aq) + 2CN^-(aq)
Anionic hydrolysis of Sr(CN)2 is basic
The hydrolysis of CN^- to gives OH^- ions . So it is basic
CN^- (aq) + H2O (l) ----------> HCN(aq) + OH^- (aq)

Why doesnt an enolate ion form in basic conditions? Why is it an addition reaction? Give the expected major organic product of each of the following reactions HOO-CH3 NaOH + CH3OH (excess) - + CH3OH (excess) →
What is the pH of a 0.47 M solution of Sr(OH)2? What is the hydrogen ion concentration?
17.61 Write the chemical equation for the formation of the Cu(CN)2 ion. Then write the K Cusunt 2 CNas expression. Culr 17.62 Write the chemical equation for the formation of the Fe(CN)63 ion. Then write the K expression.
For the following salts: NaCN, KNO3, NH4Cl, NaHCO3, Na3PO4, please classify whether acidic ,basic ,or neutral and their respective hydrolysis net ionic equation of the ion that determines the salt's classification. And, please explain why you classified the salt in an acidic/basic/neutral manner - really need thoroughness such as which of the ions are reacting and if it behaves as an acid or base AND why, AND why a specific ion would not be reactive. Thank you!!
