Interpretation Introduction

Interpretation:Whether aThiele micro melting-point technique can be used to determine the exact melting point of an unknowncompound or not needs to be determined.

Concept Introduction:The Thiele tube is used to determine the melting point of an unknown compound in quantitative analysis.

It is a laboratory glassware that is heated on an oil bath. The Thiele tube is heated with a small flame. As the boiling point of substance reaches, the heating is stopped and the temperature starts to fall which gives the idea about the boiling point of substance.

For the melting point, the temperature must be checked at which the substance starts melting.

Q. Determination of hardness by Clark's method.
4. A student received an impure sample of benzoic acid and reported the melting "mp=121.5 °C." The student reported the sample as pure since the melting too far off. What mistake was made that could have proven the sample's point as wasn't point impurity?
For measuring concentration of a sucrose solution, a polarimeter with a 15 cm tubing sample was used and observed rotation of 20 degree was measured. For calibration curve, different tubing sample with 23 cm length was used. The calibration curve α = 125C was stablished by using the 23 cm standard solution. Calculate concentration of the sucrose solution in percentage.
