What is the pH of a solution that contains [H+] = 0.0023 M? Is the solution acidic or basic? Show your work.

the solution is acidic and with a pH value of 2.7

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

So, for when [H+] = 0.0023 M

pH = -log(0.0023 M)

pH = -(-2.638)

pH = 2.638 (The minus signs cancelled out)

Round the pH value to the nearest tenth as 2.7.

On the pH scale, readings are from 1 to 14, and pH values less than 7 are regarded as acidic while pH values above 7.0 are basic.

Thus, the solution is acidic and with a pH value of 2.7

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.
