Hardness in groundwater could simply be treated by Heating the water to a considerable temperature. Chlorination and Distillation could also be applied to groundwater hardness treatment.
You could measure its resistance; the saltier it is then the better conductor it is.
Mineral: Are homogenous, naturally occuring, inorganic solids. A mineral may be a single element such as copper (Cu) or silver (Ag), or it could be a compound made up of a number of elements. Rock: Is made up of two or more minerals.
One could purchase a portable hardness tester at MCS Direct, and on Amazon. Another place to purchase a portable hardness tester online would be Martrow which offers free shipping in the United States.
An Ore.
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
You do not provide enough information for us to answer this question.
A peridot could scratch any mineral with a Mohs hardness of 6.5 or less. Click on the link below for information on the Mohs hardness scale.
You could test for hardness, streak, cleavage, fluorescence, reaction to acid, radioactivity, flame test, etc.
The most commonly known mineral that can be scratched with a fingernail is talc.
He is either investigating if it is facture or cleavage. Or he could be trying to test it's hardness. He is either investigating if it is facture or cleavage. Or he could be trying to test it's hardness.
Sometimes the concept of hardness is confused with whether or not a mineral will break. It is important to understand that even though a diamond is extremely hard, it can shatter if given a hard enough blow in the right direction along the crystal. Hope this helps!
Examples of mineral characteristics: - density - hardness - refractive index - chemical composition - magnetic properties - cleavage - crystal system - radioactivity
The mineral corundum, with a Mohs hardness of 9, will be harder than a ceramic streak plate and therefore leave no streak.
Both basalt and granite are types of rock, and a rock is composed of multiple minerals - except for some rocks composed of essentially one mineral like limestone (calcite) or quartzite (quartz). Minerals are crystalline compounds with known characteristics such as hardness, specific gravity, etc Therefore the hardness of the rock depends on the exact location on the rock you are testing the hardness, as it will vary from mineral to mineral. Some minerals even have differential hardness. Granite is composed of quartz, feldspar, and usually some ferromagnesian minerals such as biotite or hornblende (depending on the definition of a granite). Basalt is composed mostly of plagioclase (a feldspar) and pyroxene. Each of those minerals has a different hardness, and geologists never use the hardness of a "rock" to determine what kind of rock it is. Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals. On Moh's hardness scale, the hardness of these rock-forming minerals are as follows: Quartz 7 Feldspar 6 (depending on the species of feldspar) Biotite 2.5-3 Pyroxene 5-6 (depending on the species of pyroxene) So the hardness of a rock is determined by the minerals, and in a coarse grained rock like a granite, the hardness can vary widely. The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt. The resistance to breaking of a rock (which could be confused with the apparent hardness to a non-expert) is greatly affected by fractures, weathering, induration, welding, and many other features which are independent of mineral content.
Moh's Scale of Hardness # Talk # Gypsum # Calcite # Fluorite # Apatite # Orthocalse Feldspar # Quartz # Topaz # Corundum # Diamond Has only 10 minerals in it. There are literally 100s if minerals to be found in the rocks that are not used in the scale but that can have their hardness related to the scale. e.g. graphite, galena, beryl, zircon etc.
A mineral is any chemical compound with a constant chemical composition, which of course is the definition of a "pure substance". In earth science you might be distinguishing between "rock" and "mineral". A mineral is a pure substance. A rock is a mixture of two or more minerals in various proportions. For instance, the rock granite is made up of three minerals: quartz, feldspar and biotite (mica).
