This solution would be close to nuetral but slightly basic, due to there being 2 Na+ moleucles and 1 SO4-2
First.Get moles sodium sulfate.5.35 grams Na2SO4 (1 mole Na2SO4/142.05 grams)= 0.0377 moles Na2SO4-------------------------------------Second.Molarity = moles of solute/Liters of solution ( 330 mL = 0.33 Liters )Molarity = 0.0377 moles Na2SO4/0.33 Liters= 0.114 M Na2SO4=============
The answer is 20,79 mL (0,021 L).
The chemical equation is:Ba(NO3)2 + Na2SO4 = BaSO4 + 2 NaNO3The volume (in mL) of 0,25M Na2SO4 solution needed to precipitate all the barium as BaSO4(s) from 12,5mL of 0,15M Ba(NO3)2 solution is 7,5 mL.
Na+1 and I-1; the Ba+2 and SO4-2 precipitate as BaSO4.
To find the number of moles of Na2SO4 in 25.0 g of the compound, you need to convert the mass to moles. First, determine the molar mass of Na2SO4, then divide the given mass by the molar mass to obtain the number of moles.

To find the molality, we first calculate the moles of Na2SO4: 10.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 0.0705 moles Na2SO4. Then, molality is calculated as moles of solute (Na2SO4) / kilograms of solvent (water): 0.0705 mol / 1.000 kg = 0.0705 mol/kg, which is the molality of the solution.
The pH of a solution of Na2SO4 at a concentration of 0.25M is about 7, which is neutral. Na2SO4 is a salt formed from a strong base (NaOH) and a strong acid (H2SO4), so it does not significantly affect the pH of the solution.
The pH of a solution of Na2SO4 would be around 7, which is considered neutral. This is because Na2SO4 is a salt that dissociates completely in water to form Na+ and SO4 2- ions, which do not have a significant effect on the pH of the solution.
No, sodium sulfate (Na2SO4) is not soluble in benzene because it is a polar compound and benzene is a nonpolar solvent. Therefore, they will not form a homogeneous solution.
As sodium sulfite (Na2SO4) dissolves, it dissociates into its ions: Na2SO4 --> 2Na+ + SO32-
There are 0.850 moles of Na2SO4 in 325 mL of 0.850 M solution. Since Na2SO4 contains 2 sodium ions per formula unit, there will be 2*0.850 moles of sodium ions in the solution. Thus, there are 1.7 moles of sodium ions in 325 mL of 0.850 M Na2SO4 solution.
