You can determine the molar of an unknown solute from the boiling point elevation. When you do an experiment, add a certain known amount of the unknown compound to a solvent, say water. Then, determine the boiling point of the solution. The working equations would be the following:

Temp difference = Boiling pt of solution - Boiling point of pure solvent
Moles solute = (Temp difference)(Mass of solvent)/(Ebullioscopic constant of water)
Molar Mass = Mass of solute/Moles solute

The boiling point of water is 100°C,while the ebullioscopic constant is 0.512 °C/molal.

Which of the following ions is formed when a base is dissolved in a solution?
Aneli [31]

Answer:

\huge\boxed{\sf OH-}

Explanation:

<u>According to Arrhenius concept of acid and base:</u>

"When a base in a solution, produces/yields OH- (Hydroxide) ions."

So, when a base is dissolved in a solution, it produces OH- ions.

<u>For example:</u>

NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

\rule[225]{225}{2}

Hope this helped!

Give the product expected when the following alcohol reacts with pyridinium chlorochromate (PCC). (Assume that PCC is present in
Hoochie [10]

Answer:

Kindly check the explanation section.

Explanation:

Based on the description of the reacting -OH group containing Compound, the drawing of the chemical compound is given in the attached picture.

So, without mincing words let's dive straight into the solution to the question.

The reaction between the OH containing compound and PCC is an oxidation reaction.

Looking at the carbon number 1 which the first OH group and CH3 are attached to. Oxidation can not occur here as tertiary alcohol can not be oxidize.

Hence, the second OH will be oxidized into a carbonyl group, C = O. Kindly note that when alcohol oxidizes it turns into an aldehyde.

The equation for the reaction is also given the the attached picture.
