Answer: Hello There!................

Separating funnuel. AND

Explanation:

Carbon tetrachloride and water are separated by using a separating funnel. Carbon tetrachloride and water are imiscible with each other. Hence, they form two layers. The density of carbon tetrachloride is more dense than water and forms lower layer. Water being less dense, forms upper layer.

An acidic solution at 25°c will have a hydronium ion concentration ________ and a ph value ________.

lesantik [10]

The given question is incomplete. The complete question is:

An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________.

$[H_3O^+]$ > $1\times 10^{-7}$ M, pH < 7.00

$[H_3O^+]$ < $1\times 10^{-7}$ , pH < 7.00

$[H_3O^+]$ < $1\times 10^{-7}$ ,, pH > 7.00

$[H_3O^+]$ > $1\times 10^{-7}$ ,, pH > 7.00

Answer: $[H_3O^+]$ > $1\times 10^{-7}$ M, pH < 7.00

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.

$pH=-\log [H_3O^+]$

$7=-log[H_3O^+]$

$[H_3O^+]=10^{-7}$

As pH of acids is less than 7, the hydronium ion concentration is greater than

Thus the correct option is $[H_3O^+]$ > $1\times 10^{-7}$ M, pH < 7.00
