what is the ph of a solution if 10 ml of a 1 m hcl solution is added to 10 ml of a 1 m naoh solution?

Answers

Answer 1

The pH of a solution if 10 ml of a 1 M HCl solution is added to 10 ml of a 1 M NaOH solution can be calculated as follows:

First, let's find the number of moles of HCl and NaOH in the solution. Number of moles of HCl = Concentration of HCl x Volume of HClNumber of moles of HCl = 1 M x (10 ml/1000 ml)Number of moles of HCl = 0.01 molesNumber of moles of NaOH = Concentration of NaOH x Volume of NaOHNumber of moles of NaOH = 1 M x (10 ml/1000 ml)Number of moles of NaOH = 0.01 molesNext, let's find the net number of moles of H+ and OH- ions.Number of moles of H+ ions = Number of moles of NaOH - Number of moles of HCl.Number of moles of H+ ions = 0.01 - 0.01Number of moles of H+ ions = 0 molesNumber of moles of OH- ions = Number of moles of HCl - Number of moles of NaOHNumber of moles of OH- ions = 0.01 - 0.01Number of moles of OH- ions = 0 molesSince the net number of moles of H+ ions and OH- ions is zero, the solution is neutral. The pH of a neutral solution is 7. Therefore, the pH of the solution is 7.

Answers

The amount of kinetic energy required to strain the chemical bonds in substrates so they can achieve the transition state is the definition of activation energy.

What is Activation Energy?

Activation energy is the amount of energy required for a chemical reaction to occur. The energy that must be provided to molecules in order for them to react with one another is known as activation energy.

This can be accomplished in a variety of ways, such as by increasing the temperature or pressure, adding a catalyst, or irradiating the reactants with light.

Activation energy is defined as the energy required for the reaction to begin. It's the energy that molecules require to overcome the initial barrier so that a reaction may proceed.

When a chemical reaction occurs, the reactants must collide with one another with sufficient force and in the appropriate orientation to form products.

It's critical to note that activation energy is a form of potential energy that isn't included in the overall energy change of a reaction.
