HCN + H20 => CN- + H3O+
0.45 X X
Solve for X
(4.0*10^-10) = x^2/0.45M
x=1.34e-5= [OH]
Find pOH= -log of the above number
then 14-4.87=pH= 9.13

A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
What is the Lewis dot structure of the chemical equation HCN?
HCN(aq) + H2O(l) = CN^1-(aq) + H3O^1+(aq)
What is the charge of hydrocyanic acid?
Hydrogen Cyanide has the chemical formula HCN.
Is HCN linear?
HCN is a linear molecule.
What is Ka for HCN aq H aq CN aq?
ka=[H+][CN-]/[HCN]
Why is HCN soluble in water?
HCN is not soluble in water.
What is the shape of molecule of hcn?
HCN has a linear molecule.
Is hcn is a bAses?
HCN is hydrocyanic acid and is acidic (not basic).
Is HCN acid?
HCN or hydrocyanic acid is a weak acid.
Is HCN or KCIO3 a salt?
HCN is an acid; KClO3 is a salt.
Is HCN an acid or base?
Yes and no. HCN is a salt, but it is also a weak acid.
What is hcn in the periodic table?
"hcn" does not occur in a proper periodic table. "HCN" is the molecular formula for a covalent compound named "hydrogen cyanide".
