How much H2SO4 is required to prepare 250 mL solution?
To prepare 1000 mL 0.1M H2SO4 solution 0.1 mole H2SO4 = (98×0.1) g = 9.8 g H2SO4 is required. So, to prepare 250 mL 0.1N H2SO4, (250/1000)×9.8 = 2.45 g H2SO4 is required. Procedure: Take a 250 mL volumetric flask.
How to prepare a solution where the solute’s concentration is a volume percent?
To prepare a solution where the solute’s concentration is a volume percent, you measure out an appropriate volume of solute and add sufficient solvent to obtain the desired total volume.
What is the dilution of CuSO4 solution?
5.0 mL of a 0.100 M CuSO4 solution must be diluted to 10.0 mL to obtain 10.0 mL of a 0.050 M CuSO4 solution. How would you prepare 10x10^2 mL of 0.8 M H2SO4 starting with 2.08 M solution of H2SO4?
How many molecules of H2SO4 will it take to neutralize Koh?
Because 1 molecule of H2SO4 gives 2 H+ ions per molecule while only one H+ ion is required to neutralize 1 molecule of KOH. So, 1 molecule of H2SO4 can neutralize 2 molecules of KOH. Hence, we would require 525 ml of 0.03 M H2SO4 to neutralize 525 ml of 0.06 M KOH. How will we prepare 525 ml of 0.03 M H2SO4 ?
How to prepare a stock solution?
A stock solution is prepared by weighing out an appropriate portion of a pure solid or by measuring out an appropriate volume of a pure liquid, placing it in a suitable flask, and diluting to a known volume. Exactly how one measure’s the reagent depends on the desired concentration unit. For example, to prepare a solution with a known molarity you weigh out an appropriate mass of the reagent, dissolve it in a portion of solvent, and bring it to the desired volume. To prepare a solution where the solute’s concentration is a volume percent, you measure out an appropriate volume of solute and add sufficient solvent to obtain the desired total volume.
How are solutions prepared?
Solutions are often prepared by diluting a more concentrated stock solution. A known volume of the stock solution is transferred to a new container and brought to a new volume. Since the total amount of solute is the same before and after dilution, we know that
How much glacial acetic acid to add to a container?
To prepare the solution, use a graduated cylinder to transfer 80 mL of glacial acetic acid to a container that holds approximately 2 L and add sufficient water to bring the solution to the desired volume.
Can we express molarity as mol/l?
Although usually we express molarity as mol/L, we can express the volumes in mL if we do so both for both V o and V d.
How many ml of H2SO4 to 1000mL?
that means for 0.1 N H2SO4 2.77 ml of it to 1000mL of solvent.
How to make H2SO4 solution?
Procedure: Take a 250 mL volumetric flask. Pour about 150 mL distilled water in it. Then pour 2.45 g of H2SO4 in it with constant stirring. Make up the volume with distilled water up to the 250 mL mark. Your desired solution is ready.
How many moles of hydronium are in H2SO4?
The equivalent weights of solute per liter of solution of H2SO4 is 2 since in 1 mole of sulfuric acid there are 2 moles of hydronium ions.
How many moles of solute are in a molar solution?
A molar solution contains 1 mole of solute per liter of solution.
How many moles of H2SO4 are in a liter of water?
To make a 2M solution you will want 2 moles of the H2SO4 in a total of 1L of water. Given that there are 20 moles in 1L of concentrated stock solution, you can calculate that it takes a tenth of a liter
How many grams is H2SO4?
The molar mass of H2SO4 is 98 grams.The equivalent mass of 1 N solution of H2SO4 is 98 * 0.5 which is 49 grams. The 0.1 N solution has 4.9 grams per liter of solution.
What is the density of H2SO4?
As density of concentrated H2SO4 is 1.84gm/ml we will need this number as well, and as the atomic mass of H2SO4 is 98.08,as it is dibasic for normality it is 49
