Question

A 1-liter solution contains 10-8 moles of hydrogen ions. Determine whether the solution is
acidic, neutral, or basic.​

Answer 1

Answer:

Step-by-step explanation:

The solution is basic.

Answer 2

Given: A 1-liter solution contains 10-8 moles of hydrogen ions.

To find: Whether the solution is acidic, neutral, or basic.

Solution: Moles of hydrogen

$= {10}^{ - 8} moles$

Volume of solution= 1 L

Now, the concentration of H+ ions in the solution is given by

= Moles of H+ / Volume of solution

$= \frac{ {10}^{ - 8} }{1}$

$= {10}^{ - 8}$

Therefore, [H+] $= {10}^{ - 8}$

pH of the solution is given by the formula

= - log [H+]

$= - log \: {10}^{ - 8}$

= -(-8)

= 8

The solution whose pH is greater than 7 is basic, whose pH is 7 is neutral while solution whose pH is less than 7 is acidic in nature.

Here, pH is 8 which means that the solution is basic in nature.

Therefore, the solution is basic in nature.
