Question

Limit test are __________ test designed to identify and control small

quantities of impurities.

a) Qualitative b) Quantitative c) Imperative d) All of these​

Answer 1

Answer:

Quantitative

Explanation:

In general limit test is defined as quantitative or semi quantitative test designed to identify and control small quantities of impurity which is likely to be present in the substance. Limit test is generally carried out to determine the inorganic impurities present in compound..

Answer 2

Answer:

Limit test are Quantitative test designed to identify and control small quantities of impurities.

Explanation:

• Limits tests are quantitative or semiquantitative tests created to find and manage trace amounts of impurity that are most likely present in the substances.
• In order to identify the inorganic impurities contained in a compound, a limit test is typically conducted.
• Limit tests are purity testing procedures that are used to find contaminants that are commonly present but can only be tolerated in very limited amounts.
• The substance to be examined is often compared to a reference sample that has the desired impurity present in a known concentration (comparison test).
• Principle: The limit test for chloride is the precipitation reaction. When silver nitrate combines with soluble chloride to create silver chloride, which appears in the form of a solid, chlorides precipitate from soluble chloride in the presence of diluted nitric acid.
