Equal volumes of solutions with pH = 2 and pH=12 is mixed. Calculate the pH of the resulting solution?

The pH of resulting solution is 14.

Explanation:

pH of a solution is the negative logarithm of concentration of hydrogen ions.

If two or more solutions are mixed together then pH of the resulting solution is calculated as the sum of pH of all the solutions.

As pH of a given solution is 2 and pH of another solution is 12. Therefore, pH of the resulting solution is calculated as follows.

where,

= pH of solution 1

= pH of solution 2

Substitute the values into above formula as follows.

Thus, we can conclude that the pH of resulting solution is 14.

yes definetly because you are using energy

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.
