Vesnalui [34]3 years ago
7 0

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Molar mass is defined as the sum of the atoms present in a compound each multiplied with the number of atoms present in it.

For a compound A_xB_y

The molar mass will be = [(x\times \text{Molar mass of A})+(y\times \text{Molar mass of B})]

So, for the given compound NH_3,

The molar mass will be = [(1\times \text{Molar mass of Niyrogen})+(3\times \text{Molar mass of Hydrogen})]

Hence, the correct answer is Option C.

The concentration of hydroxide ions is greater than the concentration of hydronium ions for acidic solution. True or false.
larisa86 [58]

Answer: False

Explanation:

An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.

A base is defined as the substance which looses hydroxide ions when dissolved in water.

If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.

If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.

A water solution is found to have a molar oh- concentration of 3.2 x 10-5. the solution would be classified as :_______.
Anuta_ua [19.1K]

A water solution is found to have a molar oh- concentration of 3.2 x 10-5. the solution would be classified as neutral.

The concentration of hydroxide ions (OH-) is measured by pOH. It is a way of expressing how alkaline a solution is. At 25 degrees Celsius, aqueous solutions with pOH values of 7 or less are neutral, whereas those with pOH values of 7 or more are acidic. The hydrogen ion potential is known as pH. The potential of hydroxide ions is known as pOH. 2. It is a scale used to estimate the hydrogen ion (H+) concentration in the solution. The hydroxide ion (OH-) concentration of the solution is measured using this scale.

pH + pOH = 14

 pOH = 3.2x 10-5

[OH-] = 10^(-pOH) =10^(- 3.2x 10-5)

= 0.99
