HCN is a compound called hydrogen cyanide. It is commonly known as just cyanide and became infamous as a poison. It is a carbon atom, a hydrogen atom and a nitrogen atom combined in what is called a linear molecular shape. The nitrogen has 3 bonds to the central carbon, and the hydrogen has a single bond to the carbon.
ka=[H+][CN-]/[HCN]
The conjugate base of HCN is CN-. It is formed when HCN donates a proton (H+) and becomes negatively charged.
hydrogen cyanide
Yes and no. HCN is a salt, but it is also a weak acid.
The carbon atom in HCN is sp hybridized.
ka=[H+][CN-]/[HCN]
HCN is a linear molecule.
HCN has a linear molecule.
HCN is hydrocyanic acid and is acidic (not basic).
The conjugate base of HCN is CN-. It is formed when HCN donates a proton (H+) and becomes negatively charged.
HCN is an acid; KClO3 is a salt.
hydrogen cyanide
Yes and no. HCN is a salt, but it is also a weak acid.
The carbon atom in HCN is sp hybridized.
The chemical formula for hydrocyanic acid is HCN.
The chemical formula for hydrocyanic acid is HCN.
A pH of 4.29 corresponds to a hydrogen ion concentration of 10-4.29, which equals 10-5 X 10+0.71, since 0.71 - 5 = -4.29. 10+0.71 = 5.1, to the justified number of significant digits. By definition, Ka = [H+]X[CN-]/[HCN], and in the absence of other sources of cyanide anions, [H+] = [CN-]. Within the number of significant digits given, [HCN] = 0.16, and Ka then = (5.1 X 10-5)2/0.16 = 1.6 X 10-8.
