What is the Ka for hclo4?

How do you find the Ka expression?

There is a relationship between the concentration of products and reactants and the dissociation constant (Ka or Kb). For acids, this relationship is shown by the expression: Ka = [H3O+][A-] / [HA].

What is the formula for hclo4?

HClO4
Perchloric acid/Formula

What is the Ka value?

The acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates. Thus, strong acids must dissociate more in water.

How do you calculate Ka?

Chemists determine the strength of an acid (Ka) by measuring the concentrations of HA, H 30 + and A – at equilibrium and dividing the concentrations of the products by the concentration of the original acid. Because the concentration of water is a constant, they leave it out of the equation. Ka = [H 3O +] [A -]/[HA]

What is the chemical name for HClO4?

HClO4 is the chemical formula for perchloric acid. This particular acid is classified as a strong acid because of its ionizing properties in water. Strong acids are those that are able to ionize in water completely.

What is the Ka of hydrochloric acid?

Ka values can be very large or very small. For example, the Ka value for hydrochloric acid (HCl) is around 10 7, while the Ka value for ascorbic acid (vitamin C) is 1.6 X 10 -12.

What is pH of HClO4?

The pH of 0.010 M HClO4. The pH of 0.15 M propionic acid The pH of 0.10 M pyridine The pH of 0.10 M sodium bromide The pH of 0.11 M hydrazinium bromide.
