Hydrogen Cyanide
HCN will diffuse faster due to its lower molecular weight.
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.
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.
The acid in the reaction is hydrogen cyanide (HCN), which is formed when cyanide ion (CN-) reacts with water (H2O) to release hydroxide ion (OH-).
HCN stands for hydrogen cyanide, which consists of hydrogen, carbon, and nitrogen atoms. Hydrogen is in the first column (group 1) of the periodic table, carbon is in the fourth column (group 14), and nitrogen is in the fifteenth column (group 15).
The IUPAC name is formonitrile, the common used name is hydrogen cyanide.
The compound name of the formula HCN is hydrogen cyanide.
It is hydrogen cynide , highly harmful and hazardous for life.
ka=[H+][CN-]/[HCN]
HCN is a linear molecule.
hydrocyanic acid
HCN has a linear molecule.
hydrocyanic acid
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.
