What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
Is normality and molarity for sodium thiosulfate same?
No, normality and molarity are not the same for sodium thiosulfate. Molarity is a measure of the concentration of a solution based on the number of moles of solute per liter of solution, while normality is a measure of the concentration of a solution based on the equivalent weight of the solute. The normality of sodium thiosulfate will depend on the number of equivalents of the solute present in the solution.
What is made when iron sulphate and sodium carbonate are mixed?
When iron sulfate and sodium carbonate are mixed, iron carbonate and sodium sulfate are produced. Iron carbonate is a solid precipitate that can be formed during the reaction, while sodium sulfate remains in solution.
What happens when sodium sulphate is added to barium nitrate?
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
Is sodium sulphate aqueous?
Sodium sulfate can exist in an aqueous solution but it can also exist on its own as a crystalline solid.
How many grams of sodium sulfate Na's must be added to make 500 ml of M sodium sulfate solution?
To determine the grams of sodium sulfate needed, you first need to specify the molarity (M) of the sodium sulfate solution. Once you have the molarity, you can use the formula: grams = molarity (M) x volume (L) x molar mass (g/mol). This will give you the amount of sodium sulfate in grams needed to make the solution.
What is the molarity of a 0.75 L solution that contains 9.1 g sodium chloride?
This molarity is 0,207 mol.
How do you prepare sodium sulphate solution?
To prepare a sodium sulfate solution, dissolve a known amount of sodium sulfate powder in a known volume of water. You can calculate the molarity of the solution by knowing the mass of sodium sulfate and final volume of the solution. Be sure to wear appropriate personal protective equipment and work in a well-ventilated area when handling chemicals.
The molarity of a 10.0 L aqueous solution that contains 23.4 grams of sodium chloride is?
The first step is to convert the mass of sodium chloride to moles using its molar mass. Then, divide the moles of sodium chloride by the volume of the solution in liters to calculate the molarity.
What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
What is the molarity of sodium borate?
The molarity of sodium borate (Na2B4O7) would depend on the concentration of the solution. To calculate molarity, you would need to know the amount of sodium borate dissolved in a known volume of solvent. Molarity is expressed in moles of solute per liter of solution.
Composition of 1 liter Benedict's solution?
Benedict's solution typically contains copper(II) sulfate, sodium citrate, and sodium carbonate. The exact composition can vary, but a common formulation is 17.3 g copper(II) sulfate, 100 g sodium citrate, and 173 g sodium carbonate per liter of water.
What is the molarity of 6.2L of solution if it contains 2.5 moles if sodium chloride?
Molarity means moles per litre. You have to bring the ratio to moles per a litre. So, 2.5 divided by 6.2 is 0.403 molar.
What is the molarity of 6.2 L of solution if it contains 2.5 moles of sodium cholride?
The molarity of a solution is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, you have 2.5 moles of sodium chloride in 6.2 L of solution. Thus, the molarity is 2.5 moles / 6.2 L = 0.40 M.
How do you test for sodium sulfate?
One common method to test for sodium sulfate is by performing a precipitation reaction. Mixing a solution of sodium sulfate with a solution of barium chloride will result in the formation of a white precipitate of barium sulfate. The presence of this precipitate confirms the presence of sulfate ions, indicating the presence of sodium sulfate in the original solution.
What is the reaction between sodium shalphate and water?
Sodium sulfate dissolves in water to produce a solution of sodium sulfate.
What is the molarity of a solution of sodium hydroxide if it contains 0.5 moles in 75mL of solution?
Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.
