Interpretation Introduction

Interpretation:

“Give an explanation for each of the following observation.”

a. Methanol is soluble in water, but ethane is not.

b. 2-Propanol is soluble in water, but 1-butanol is only slightly soluble.

c. 1-Porpanol is soluble in water, but ethyl methyl ether is only slightly soluble, should be explained

Concept introduction:

► Polarity of any substance is measuring as dipole moment and solubility of any substance depends on the following fact:

“like dissolves like”

► The solubility of solute in solvent is depending on the size of solute. Solubility is reciprocal to the size of solute means if the size of solute is small then solubility is greater and if the size of solute is big then solubility is lower.

$solubiliy of solute \propto \frac{1}{size of solute}$

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
