Question

Consider the following experimental section.

Vitamin C content was determined by the standard titration method with 2,6dichlorophenolindophenol.

• 100g of leaves are weighed for each samples, blended in water for 1 minute and filtered before being titrated.

Choose all answers that apply to it.

Then, based on your choices, assign the Experimental section one of the following quality categories:

You were in agreement with more than 75% of the statements - GOOD

You were in agreement with 50% - 75% of the statements - MEDIUM

You were in agreement with fewer than 50% of the statements - POOR

The Experimental section describes what was studied.

The control is identified.

The measured variables are identified.

The experimental conditions are described.

The method used to determine vitamin C includes enough information for another chemist to replicate the experiment.

This is a GOOD quality Experimental section.

This is a MEDIUM quality Experimental section.

This is a POOR quality Experimental section.

This is a POOR quality Experimental section.

From the given information, it can be said that

a. The Experimental section describes what was studied.

c. The measured variables are identified.

In agreement with fewer than 50 % of the statements. This is a POOR quality experimental section.
