Percent by mass of nitrogen = 63.7%. WebHydrogen cyanide is weakly acidic with a pKa of 9.2. An example would be water ($\mathrm{p}K_\mathrm{a} = 15.7$ therefore $\mathrm{p}K_\mathrm{b}(\ce{OH-}) \approx -1.7$) which is a weak acid with a strong conjugate base. A:Acidic and basic solutions can be differentiated from pH scale. ---> Shouldn't the product formed depend on the alkyl group, say for a tertiary alkyl group, the reaction can go via $\mathrm{S_N1}$ mechanism for polar protic solvents and via $\mathrm{E2}$ for polar aprotic solvents and as the cyanide ion is strong base, the reaction is unlikely to go via $\mathrm{E1}$ and due to steric factors $\mathrm{S_N2}$ is also ruled out. with water. There are two calculators one for either strong acid or strong base, and another for either weak acid or weak base. basic salt: the product of the neutralization of a strong base and a weak acid; its anion is the conjugate base of the weak acid.

What type of solution forms when a nonmetal oxide dissolves in water? Cyanides are weak bases when dissolved in water pKb=4.8. The word generally is required here, since compounds such as $\ce{H2Cl+}$ are very strong acids whose conjugate bases are still very strong but these compounds are not typically easily accessable and certainly not in aquaeous solution. Answer = SiCl2F2 is Polar What is polarand non-polar? Since it is such a weak base, it has no access to $\mathrm{E2}$ pathways and $\mathrm{E1}$ pathways are disfavoured against $\mathrm{S_N1}$ if either is applicable.
