Chemistry
1 answer:
sergejj [24]2 years ago
3 0

Considering a simple distillation in the laboratory

3) The content of the distillate is : Alcohol and water

  The residue is : water

4) The literature boiling point = 151°F

   The Observed boiling point = 147°F

Distillation is a simple method used in the laboratory to separate the contents of a mixture based on the differences in their volatilities when mixture is heated to a boiling point.

My assumption; on a simple distillation experiment consists of a mixture containing methanol ( alcohol ) and water

Hence the content of the distillate is ; Alcohol and water the residue is water while the literature boiling point is 151°F and the observed boiling point is 147°F

24. What volume of a 0.0200M calcium hydroxide is required to neutralize 35.00 mL of 0.0500M nitric acid
Natalka [10]

Answer:

THE VOLUME OF 0.200M CALCIUM HYDROXIDE NEEDED TO NEUTRALIZE 35 mL of 0.050 M NITRIC ACID IS 43.75 mL.

Explanation:

Using

Ca VA / Cb Vb = Na / Nb

Ca = 0.0500 M

Va = 35 mL

Cb = 0.0200 M

Vb = unknown

Na = 2

Nb = 1

Equation for the reaction:

Ca(OH)2 + 2HNO3 --------> Ca(NO3)2 + 2H2O

So therefore, we make Vb the subject of the equation and solve for it

Vb = Ca Va Nb / Cb Na

Vb = 0.0500 * 35 * 1 / 0.0200 * 2

Vb = 1.75 / 0.04

Vb = 43.75 mL

The volume of 0.02M calcium hydroxide required to neutralize 35 mL of 0.05 M nitric acid is 43.75 mL
