What is the pH of an HCL solution if [H+]=0.03

pH = 1.5

Explanation:

The pH is always equal to -log[H+].

Simply plug it into this formula to find the pH. In order to find the concentration from the pH, you can do:

= [H+]

The answer for the following problem is mentioned below.

Explanation:

pH:

It is a measure of the hydrogen ion concentration,a measure of acidity or the alkalinity of a solution.    

                                           (or)

The negative logarithmic function of the hydrogen ion concentration is called the pH.

The formula for the pH is as follows:

pH = -log []

pH less than 7 indicates that solution is acidic

pH greater than 7 indicates that the solution is basic

Given:

hydrogen ion concentration [] = 0.03 = 3 ×

To calculate:

pH of a solution

We know;

pH = -log []

where,

represents the hydrogen ion concentration

pH = -log [3×10^-2]

pH = 1.52

Therefore the pH of a solution is 1.52

Therefore the pH of an HCl solution is 1.52.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
