What two tests would you use to identify talc?
To identify talc, you could use the Mohs hardness test to determine its hardness, as talc has a low hardness of 1 on the Mohs scale. Additionally, you could perform a scratch test where talc can be easily scratched with a fingernail due to its softness.
What is the Mohs hardness test?
The Mohs hardness scale is basically a scale used for determining how hard a mineral. More specifically the scale measures the ability of one mineral to scratch another. The Mohs scale ranges from 1 to 10, 1 being the softest and 10 being the hardest. Some examples by hardness include: 1. Talc 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Ruby 10. Diamond
Scratching a mineral with a nail is a test of what?
Scratching a mineral with a nail is a test of hardness. It helps determine the relative hardness of the mineral compared to known substances on the Mohs scale of mineral hardness.
What type of mineral property is tested by the scratch test?
The scratch test measures a mineral's hardness, which is its resistance to being scratched. This property is identified by comparing the hardness of a mineral to the hardness of known minerals on the Mohs scale.
Devised a scale to test the hardness of minerals?
The hardness of minerals is commonly tested using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch each other. The scale was devised by Friedrich Mohs in 1812 and is still widely used in geology and mineralogy for identifying and comparing the hardness of different minerals.
What two tests would you use to identify talc?
To identify talc, you could use the Mohs hardness test to determine its hardness, as talc has a low hardness of 1 on the Mohs scale. Additionally, you could perform a scratch test where talc can be easily scratched with a fingernail due to its softness.
What is mosh and scale of hardness?
Mohs' scale of hardness is a test created by mineralogist Friedrich Mohs, which determines the relative hardness of minerals, on a hypothetical scale of 1-10, where 1 is very soft (eg Talc) and 10 is extremely hard (eg Diamond).
Scratching a mineral with a nail is a test of?
Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.
A scale used to measure the hardness of rocks?
The Mohs scale is used to determine the relative hardness of minerals.
What does Mohs Scale test?
Relative mineral hardness.
What is used to test the hardness of minerals?
the mohs scale
Who devised scale to test the hardness of minerals?
Friedrich Mohs
What is the Mohs hardness test?

Topaz 9. Ruby 10. Diamond
What is 1 of test mineralogist use on minerals?
One common test that mineralogists use is the hardness test, which is often conducted using Mohs scale of mineral hardness. This scale ranks minerals from 1 (talc) to 10 (diamond) based on their ability to scratch one another. By scratching a mineral against reference materials of known hardness, mineralogists can determine its hardness and gain insights into its identity and properties.
Scientists usw this to determine a mineral's resistance to being scratch?
Scientists use the hardness test, and more specifically Mohs Hardness Scale, named after a Freidrich Mohs, a German mineralogist. Mohs Hardness Scale test can scale from 1 to 10, where 1 is softest and 10 is hardest.
How do you test a mineral for hardness?
Well. You can do many things like use the Mohs Hardness Scale or determine the hardness by the streak.
How can you tell Talc and corundum apart?
Talc and corundum can be distinguished primarily by their hardness and appearance. Talc is the softest mineral on the Mohs scale, with a hardness of 1, while corundum is much harder, rated at 9. Additionally, talc typically has a greasy feel and a pearly luster, whereas corundum has a more glassy appearance and can be found in various colors, including blue (sapphire) and red (ruby). Visual observation of these characteristics, along with a simple scratch test, can help differentiate the two.
