What will happen if heat crystals of CuSO4 pentahydrate in a test tube and note the water given off allow to cool and compare the color of anhydrous CuSO4 with original crystals?
Heating crystals of CuSO4 pentahydrate in a test tube will cause the water molecules trapped in the crystal lattice to evaporate, leaving behind anhydrous CuSO4 crystals. The color change observed will be from blue (for the hydrated form) to white (for the anhydrous form).
Is there a way that one can calculate the degree of hydration in a given substance?
Yes, the degree of hydration in a substance can be calculated by determining the amount of water molecules present in the formula. This involves comparing the molar mass of the hydrated compound with the anhydrous compound to find the number of water molecules per formula unit.
How much CaCl2.6H2O and water must be weighed to prepare 100g of a solution that is 5 percent CaCl2?
do you mean 100 ml? most solutions are given in terms of volume not mass. But ...CaCl2 has a molar mass of 111 g The hydrated form also contains 108 g water. This gives a total mass of 219 g for the hydrated form.The solution must contain: 100 g x 5% = 100 x 5/100 = 5g anhydrous CaCl25 / x = 111 / 219solve for x: x = 5(219)/111 = 9.865 g of the hydrate
What ternary ionic compound is given to a stabilize manic-deppressive patients?
Lithium carbonate, with formula Li2CO3.
How do you calculate the molar mass of anhydrous sodiumcarbonate when given malar mass of hydrated sodiumcarbonate as 231.5gmol?
The molar mass of anhydrous sodium carbonate is 105,9888 g.
How many moles of sodium carbonate were present in 2 grams of hydrated sodium carbonate?
To determine the number of moles of sodium carbonate in 2 grams of hydrated sodium carbonate, we first need to calculate the molar mass of Na2CO3·xH2O. Once we have the molar mass, we can use the formula: Moles = Mass / Molar mass. Given that hydrated sodium carbonate has the molar mass of Na2CO3·xH2O, we can determine the number of moles in 2 grams of the compound.

How many moles of sodium carbonate are contained by 57.3g of sodium carbonate?
To find the number of moles of sodium carbonate in 57.3g, divide the given mass by the molar mass of sodium carbonate. The molar mass of sodium carbonate (Na2CO3) is 105.99 g/mol. Therefore, 57.3g / 105.99 g/mol = 0.54 mol of sodium carbonate.
What is the Frame structure of Serial Line Internet Protocol?
Preparation of standard solution and standardization of hydrochloric acid Objective : To prepare a standard solution of sodium carbonate and use it to standardize a given solution of dilute hydrochloric acid. Introduction : Anhydrous sodium carbonate is a suitable chemical for preparing a standard solution (as a primary standard). The molarity of the given hydrochloric acid can be found by titrating it against the standard sodium carbonate solution prepared. The equation for the complete neutralization of sodium carbonate with dilute hydrochloric acid is Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l) The end-point is marked by using methyl orange as indicator. Chemicals :solid sodium carbonate, 0.1 M hydrochloric acid
How do you calculate Assay of Ceftriaxone sodium BP on anhydrous basis?
To calculate the assay of Ceftriaxone sodium BP on an anhydrous basis, you first need to determine the molecular weight of Ceftriaxone sodium. Next, you would divide the weight of the anhydrous Ceftriaxone sodium by the total weight of the sample and multiply by 100 to get the percentage on an anhydrous basis. This calculation helps ensure accurate dosing and purity of the compound.
What is 45 mL of 0.12 M sodium carbonate?
It is a solution whose strength and quantity are given .
What language dose sodium come from?
The element sodium gets its name from the English word "soda" because it was first isolated by Humphry Davy through the electrolysis of sodium hydroxide (caustic soda). Sodium's chemical symbol, Na, comes from the Latin word "natrium."

Why is sodium given that name?
The name sodium probably originates from the Arabic word suda meaning headache as the headache-alleviating properties of sodium carbonate or soda were well known in early times.
How many moles of sodium carbonate are present in 212g?
To calculate the number of moles of sodium carbonate in 212g, you need to first determine the molar mass of Na2CO3 (sodium carbonate). The molar mass of Na2CO3 is 105.99 g/mol. Then, you divide the given mass (212g) by the molar mass to find the number of moles (212g / 105.99 g/mol = 1.999 moles).
What is the chemical change in baking soda?
Baking Soda is Sodium hydrogen carbonate(NaHCO3). When heat is given, it decomposes into Sodium carbonate(Na2CO3), Steam(H2O) and Carbon dioxide(CO2), according to the following equation:2 NaHCO3 --Δ--> Na2CO3 + H2O + CO2
