Find the concentration of H+ ions at a pH = 11 and
Black_prince [1.1K]

Explanation:

the pH of the solution defined as negatuve logarithm of H^+ ion concentration.

pH=-\log[H^+]

1. Hydrogen ion concentration when pH of the solution is 11.

11=-\log[H^+]

[H^+]=1\times 10^{-11} mol/L..(1)

At pH = 11, the concentration of H^+ ions is 1\times 10^{-11} mol/L.

2. Hydrogen ion concentration when the pH of the solution is 6.

6=-\log[H^+]'

[H^+]'=1\times 10^{-6} mol/L..(2)

At pH = 6, the concentration of H^+ ions is 1\times 10^{-6} mol/L.

3. On dividing (1) by (2).

\frac{[H^+]}{[H^+]'}=\frac{1\times 10^{-11} mol/L}{1\times 10^{-6} mol/L}=1\times 10^{-5}

The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is 1\times 10^{-5}.

4. Difference between the H^+ ions at both pH:

1\times 10^{-6} mol/L-1\times 10^{-11} mol/L=9.99\time 10^{-7} mol/L

This means that Hydrogen ions in a solution at pH = 7 has 9.99\time 10^{-7} mol/L ions fewer than in a solution at a pH = 6

Vera_Pavlovna [14]

Answer:

Energy is transferred from one object to another when a reaction takes place.

Explanation:

Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few.  

The answer could be It is a well known fact that energy can neither be created and nor be destroyed but can be transformed from one form to another.

Now talking about your example in a typical light bulb electrical energy is converted into light energy and heat energy. Now when the electric current flows through the conductor/filament in the light bulb,this would cause vibrations and the free ions are more likely to go to an higher energy level,and when the ions come back to their original state,the difference in the two energy levels is usually emitted as a photon,thus light energy is obtained and the heat energy is the energy dissipated as a result of flow of electricity through the conductor.

Anything that gets transformed into light energy or in better words ElectroMagnetic Energy would be a result of this.
