What is the molecular weight of CaCO3?
What is the molecular weight of CaCO3?
100.0869 g/mol
Calcium carbonate/Molar mass
What is the physical state of CaCO3?
Calcium carbonate appears as white, odorless powder or colorless crystals. Practically insoluble in water.
How do you dissolve CaCO3?
Calcium carbonate will dissolve quickly in a strong acid, like hydrochloric, even if it is dilute and therefore not so dangerous.
Is Ca2+ a weak base?
No. It is a salt of the calcium, ion a strong base and carbonic acid, a very weak acid.
What is the cation of CaCO3?
Formula and structure: The calcium carbonate chemical formula is CaCO3 and its molar mass is 100.0869 g mol-1. The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3-2. Physical properties: Calcium carbonate is an odorless, tasteless, white and fine powder.
What is the anion for CaCO3?
Calcium carbonate is made up of polyatomic carbonate anions, CO32- and monatomic calcium cations, Ca2+.
Is CaCO3 a strong base?
It’s a salt of a strong base Ca(OH)2 and a weak acid H2CO3. CaCO3 (calcium carbonate, a.k.a. chalk) doesn’t dissolve in water, so it doesn’t behave like a base. All acids stronger than H2CO3 (provide their calcium salts dissolve well in water) react with calcium carbonate, yielding CO2.
What is the equivalent mass of CaCO3?
CaCO3,which is Calcium Carbonate. It’s equivalent mass is 50 g . Then, the equivalent mass of CaCO3 is 100g/2=50g . Thus,The equivalent mass of Calcium Carbonate is 50g.
How to calculate alkalinity as concentration of CaCO3?
The amount of alkalinity in the sample is calculated using the formula shown: Alkalinity, mg/L as CaCO3 = (mL H2SO4 x NH2SO4 x 50,000) mL of sample In the equation above, 50,000 represents the equivalent weight of CaCO3 (50) multiplied by 1,000 mg. Fifty thousand is a constant used in the formula.
What is the molar mass of CaCO3?
The average molar mass of the chemical compound calcium carbonate is 100.087 grams per mole
