Arsenik Test Kits - Prosedur Pemeriksaan (Cara Pengujian)

Summary

In this video, viewers are guided through the process of testing arsenic levels in samples. The procedure includes using specific chemicals like Arsenic 1 and Arsenic 2, along with a sample and aquadest for blank comparison. The test involves adding reagents, creating a yellow solution that darkens with higher arsenic levels. A positive result is indicated by the formation of an orange precipitate. The video concludes with a promotional message, encouraging viewers to purchase the product through a link provided in the description.

Q & A

What is the primary focus of this video?

The video focuses on the procedure for arsenic testing in samples using the Regent Kids arsenic testing kit.

What materials are needed for this arsenic test?

The materials needed include arsenic 1, arsenic 2, aquadest, a sample to test, a test tube, a pipette, and a standard arsenic color chart.

What is the purpose of the blank solution (aquades) in the test?

The blank solution, consisting of aquades, is used as a reference to ensure no arsenic contamination in the test setup.

How many drops of arsenic 1 and arsenic 2 are added to the sample?

One drop of arsenic 1 and two drops of arsenic 2 are added to the sample.

What happens after arsenic 1 and arsenic 2 are added to the sample?

After adding arsenic 1 and arsenic 2, the solution is mixed thoroughly, and if arsenic is present, a yellow color will form, with the intensity depending on the arsenic concentration.

What role does Xenyx play in the test procedure?

Xenyx is added to the solution to initiate the final reaction, which helps to form a visible color change in the test solution.

What color indicates a high level of arsenic in the sample?

If the arsenic level is high, an orange precipitate will form, signaling a positive arsenic result.

How does the color of the solution indicate the arsenic concentration?

A pale yellow color indicates a low arsenic concentration, while the yellow color becomes more intense as the arsenic level increases.

What is the significance of the standard color chart used in the test?

The standard color chart is used to visually compare the test results, helping to determine the exact level of arsenic based on the color intensity.
