Calculate the ratio of H ions to OH– ions at a pH = 7. Find the concentration of H ions to OH– ions listed in Table B of your Student Guide. Then divide the H concentration by the OH– concentration. Record this calculated ratio in Table A of your Student Guide. Compare your approximated and calculated ratios of H ions to OH– ions at a pH = 7. Are they the same? Why or why not? Record your comparison in Table A. What is the concentration of H ions at a pH = 7? mol/L What is the concentration of OH– ions at a pH = 7? mol/L What is the ratio of H ions to OH– ions at a pH = 7? :1.

Sagot :

The pH can be defined as the measure of the acidity or the basicity of the solution. The ratio of hydrogen ion concentration and hydroxide ion concentration at pH 7 is 1.

What is hydrogen ion concentration?

The hydrogen ion concentration can be given as the amount of hydrogen percent in the sample solution.

The pH has been the negative logarithmic value measurement of the hydrogen ion in the sample. The sum of the hydrogen ion and the hydroxide ion in the sample has been a constant 14.

[tex]\rm pH+pOH=14[/tex]

The pH can be given as:

[tex]\rm pH=-log[H^+][/tex]

At pH 7 neutral pH the concentration of Hydrogen ion and hydroxide are equal i.e.

[tex]\rm 7=-log[H^+]\\H^+=10^{-7}\;M[/tex]

The hydroxide ion concentration has been given as:

[tex]\rm pOH=-log[OH^-]\\7=-log[OH^-]\\OH^-=10^{-7}\;M[/tex]

The concentration of hydrogen and hydroxide are equal at pH 7. Thus, the ratio of the concentration has been 1.

This states the sample to be neutral.
