Question

Identify each of these substances as acidic, basic, or neutral.
rainwater, pOH = 8.5
cola, pOH = 11
tomato juice, POH = 10
liquid drain cleaner, poH = 0

Answer 1

Answer:

Rain Water: Acidic

Cola: Acidic

Tomato Juice: Acidic

Liquid Drain Cleaner: Basic

Answer 2

Rain Water: Acidic

Cola: Acidic

Tomato Juice: Acidic

Liquid Drain Cleaner: Basic

pH

If the value of pH is 7, then the solution is neutral, if greater than 7 then basic, and if less than 7 then acidic.

The relation between pH and pOH is as follows:-

$pH+pOH=14$

The value of pH for rain water is 14-8.5=5.5.

So, the rain water is acidic.

The value of pH for cola is 14-11=3.

So, the cola is acidic.

The value of pH for tomato juice is 14-10=4.

So, the tomato juice is acidic.

The value of pH for liquid drain cleaner is 14-0=14

So, the liquid drain cleaner is basic.
