Which minerals would scratch apatite?
Apatite has a hardness of 5 on the Mohs scale, meaning that minerals with a hardness greater than 5 can scratch it. Examples of such minerals include quartz (hardness 7), topaz (hardness 8), corundum (hardness 9), and diamond (hardness 10). These minerals, due to their higher hardness, can effectively scratch apatite.
What is the name of the complexing agent used to determine the total hardness?
caco3
What can a tanzanite scratch?
Tanzanite has a hardness of 6 to 7 on the Mohs scale, meaning it can scratch materials that are softer than it. This includes minerals like gypsum (hardness 2) and calcite (hardness 3). However, it can be scratched by harder materials, such as quartz (hardness 7) and topaz (hardness 8), so care should be taken to avoid contact with such substances.
What is difference between carbonate and noncarbonate hardness?
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.
What are 2 objects that will scratch fluorite?
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.

what is the meaning of Scleroderma?
A disease of adults, characterized by a diffuse rigidity and hardness of the skin.

Why Patton's and reeder's reagent is not used for the determination of total hardness of water?
Patton's and Reeder's reagent is not used for determining total hardness of water because it specifically measures only calcium and magnesium ions, which are components of hardness but not the totality of it. Total hardness includes all divalent and trivalent cations, and relying solely on this reagent could overlook other contributing ions. Additionally, the method may not provide accurate results in the presence of other complexing agents or in varying pH conditions, limiting its applicability for comprehensive hardness assessment.

How do you calculate the total hardness of a substance?
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).
How do you raise the total hardness in pool?
You can raise the total hardness in a pool by adding calcium chloride or calcium chloride dihydrate. Follow the manufacturer's instructions for the correct dosage based on your pool's size and current hardness levels. It's important to test the water regularly to ensure the hardness remains within the recommended range.
What is the hardness of chalk?
There are a couple of things that make chalk hard. The calcium in chalk is said to make chalk hard.
