# What is the Ka for HNO2?

## What is the Ka for HNO2?

The Ka price of nitrous acid, HNO2, is 4.Zero x 10^-4.

How do you write Ka expression?

General Ka expressions take the form Ka = [H3O+][A-] / [HA]. General Kb expressions take the shape Kb = [BH+][OH-] / [B]. When using Ka or Kb expressions to resolve for an unknown, make sure to write out the dissociation equation, or the dissociation expression, first.

What is the Ka expression for acetic acid?

The equilibrium consistent for this expression is known as the acid dissociation consistent, Ka….

Weak Acid Equation Ka
acetic acid HC2H3O2 H+ + C2H3O2- 1.8 × 10-5
benzoic acid C6H5CO2H H+ + C6H5CO2- 6.4 × 10-5
chlorous acid HClO2 H+ + ClO2- 1.2 × 10-2

### What is the equilibrium consistent for the neutralization of nitrous acid with ammonia?

Question: What Is The Approximate Value Of The Equilibrium Constant, Kn, For The Neutralization Of Nitrous Acid With Ammonia, Shown In The Equation Below? The Ka For HNO2 Is 4.Five X 10-4 And The Kb For NH3 Is 1.8 X 10-5.

What is acid and base equilibrium?

Acids and bases have a chemical equilibrium in solution. At chemical equilibrium, the products and reactants have reached a state of steadiness. Concepts related to acid base equilibrium come with designing buffers and plotting pH curves. …

Why is a reaction involving a powerful acid not regarded as an equilibrium reaction?

In a strict sense the robust acid do “have an equilibrium” because any response you’ll write down and balance may have an equilibrium constant, calculable thru Nernst equation. However, the equilibrium is inconsequential except in excessive stipulations. Any acid with pKa<0, or equivalently Ka>1 is a strong acid.

## Which of the following is robust acid and strong base response?

An example of this is able to be the titration of hydrochloric acid (strong acid) and sodium hydroxide (robust base) to form sodium chloride and water. Created through Jay.

What occurs when a vulnerable acid reacts with a robust acid?

A strong acid will react with a strong base to form a neutral (pH = 7) solution. A weak acid will react with a powerful base to shape a elementary (pH > 7) answer.
