Total hardness refers to the overall concentration of calcium and magnesium ions in water. These ions can create issues such as scale buildup in pipes and appliances. Total hardness is often measured in parts per million (ppm) or milligrams per liter (mg/L).
caco3
Carbonate hardness is the measure of hard ions associated with carbonate and bicarbonate anions contained in the water.Noncarbonate hardness is the portion of total hardness in water that is not produced by carbonates, but primarily by sulfate anions.

Fluorite has a Mohs hardness of 4, meaning it can be scratched by objects with a hardness greater than that. Two common objects that can scratch fluorite are quartz, with a hardness of 7, and topaz, which has a hardness of 8. These minerals are significantly harder than fluorite and will easily leave scratches on its surface.
Calcite has a hardness of 3 on the Mohs scale, meaning it is relatively soft and can be scratched by harder materials. It is composed of calcium carbonate and is commonly found in sedimentary rocks such as limestone and marble.
hardness is how easily a mineral can be scratched

To calculate the total hardness of a substance, you add the concentrations of calcium and magnesium ions in the substance. This is typically measured in milligrams per liter (mg/L) or parts per million (ppm).
Oh, dude, raising the total hardness in a pool is like adding calcium hardness increaser. You know, it's like giving your pool a little boost of calcium to make it feel all fancy and stuff. Just follow the instructions on the product, and your pool will be harder than a rock in no time.
There are a couple of things that make chalk hard. The calcium in chalk is said to make chalk hard.
Abnormal hardness and density of bone.
Buffer ammonia is used in water total hardness tests to maintain a stable pH level during the titration process. The presence of ammonia helps prevent fluctuations in pH that could affect the accuracy of the hardness test results.
