What is the ph of a 0.014 M HCL solution?
Allushta [10]

Answer:

pH = 1.853

Explanation:

For every mole of hydrochloric acid, one mole of hydronium ion is required. Thus, in order to neutralize 0.014 moles of HCL, 0.014 moles of hydronium is required.

[H_3O^+] = [HCl] = 0.014

pH  = -log [H^+] = -log [H_3O^+]

Substituting the available values in above equation, we can say that   the pH of the solution is equal to

- log (0.014)

pH = 1.853

pH of a 0.014 M HCL solution = 1.853

What is the effect on the equilibrium when sodium formate is added to a solution of formic acid? hcooh( aq) + h ( aq) right arro
artcher [175]

There is no effect on the equilibrium when sodium formate is added to a solution of formic acid for hcooh( aq) + h ( aq) right arrow choo –( aq).

Equilibrium is characterized as a state of equilibrium or a stable situation in which conflicting forces balance one another out and no changes are taking place. In terms of economics, equilibrium occurs when supply and demand are equal. When you are composed and steady, you are in an equilibrium state.

An object is considered to be in an equilibrium condition when all of the forces acting on it are in balance. If the upward forces are equal to the descending forces and the rightward forces are equal to the leftward forces, then the forces are said to be balanced. Several instances of equilibrium include a book that is open and at rest. a vehicle that is going steadily.
