A solution contains 0.0000001 (10-7) moles of hydroxyl ions (OH-) per liter. Which of the following best describes this solution? basic: H+ donor basic: H+ acceptor acidic: H+ acceptor neutral acidic: H+ donor

Answer 1

Answer: neutral

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

`pH=-\log [H^+]`

`pOH=-\log[OH^-]`

Putting in the values:

`pOH=-\log[10^(-7)]`

`pOH=7`

`pH+pOH=14`

`pH=14-7=7`

Thus as pH is equal to 7, the solution is neutral and nether accepts
`H^+` nor donates
`H^+`.
