Is the flame test a qualitative or quantitative test for the identity of an unknown?
The flame test is a qualitative test. It is used to identify the presence of certain metal ions in a sample based on the color of the flame produced when the sample is heated.
A flame test only tells you what element you have, not how much there is.
The falme test is qualitative - it can not give you quantity - unless the flame is in an atomic absorption machine

Which one is for measuring qualitative or quantitative?
Quantitative data is measured using numerical values, such as height or weight, while qualitative data is measured by characteristics or attributes, like color or texture. The tools and methods used to measure quantitative data are typically statistical in nature, focusing on numbers and calculations, while those used to measure qualitative data often involve observations, descriptions, or categorizations.
How do you test for the presence of barium ion?
A simple qualitative test is the flame test: barium has a pale/apple green color.
Why does when an unknown sample of a metal is placed in a flame a bright green light is released?
A green flame is due probable to copper.
when is flame test used?
to identify an unknown sample by its emission spectrum
What is the purpose of putting salts of various metals into fireworks?
The flame test is a simple method for quantitative analysis for some metals.
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
Is a flame test qualitative or a quantitative analysis?
A flame test is a qualitative analysis technique used to identify the presence of specific elements based on the color of the flame produced. It is not typically used for quantifying the amount of the element present in a sample.
Is a hot flame a qualitative or quantitative measurement?
A hot flame is a qualitative measurement, as it describes the subjective perception of the flame's temperature based on sensory experience rather than a precise numerical value.
5 example of qualitative and quantitative observations before burning a candle.?
qualitative - smells of smoke, hot air from flame, flame is orange and blue at the bottom, flame moves around, [unscented candle - no smell], wick is burning and turning black. quantitative - sorry i don't have the answer. I'm looking for it myself :(
Why is atomic absorption not used for qualitative analysis?
Atomic absorption spectroscopy is not commonly used for qualitative analysis because it only provides information about the presence of a particular element in a sample, not its identity. Other techniques such as atomic emission spectroscopy or mass spectrometry are more suitable for qualitative analysis as they can provide information about the identity of elements present in a sample.
What Qualitative observations would you discover after ligting a candle?
Colour of the flame would be one.
When is the flame test applicable?
The flame test is applicable in qualitative analysis of elements, where metal ions present in a sample can be determined by the characteristic color they emit when heated in a flame. It is commonly used in chemistry labs to identify certain metal ions based on the color of the flame produced.
What was the flame test original use?
The flame test was originally used as a qualitative analysis technique in chemistry to identify the presence of certain metal ions in a compound based on the color emitted by the flame when the compound is burned. This method is still used today in chemical analysis and identification of elements.

What do you observe in unlit candle qualitative?
In an unlit candle, the qualitative observations would be its solid wax structure, the presence of a wick, and the lack of a flame or melted wax.
What is the flame color of the compound sodium chloride when heated?
No, sodium chloride is a very stable compound
What information does a flame test provide?
The emission spectrum of an element
