Using a pipette with air bubbles leads to errors.
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
It is related to concentration, which you do not give.
Aqua regia decomposes into Nitric Oxide and chlorine
The chemical reaction (a dehydration reaction) is:C12H22O11 + H2SO4 = 12 C + 11 H2O
H2SO4 is a highly concentrated acid.
If water is present in the volumetric flask when transferring the H2SO4 solution from the pipette, the final concentration of H2SO4 will be diluted. This is because the water will mix with the H2SO4 solution, increasing the total volume in the flask without adding more H2SO4 molecules. As a result, the concentration of H2SO4 will be lower than intended.
The concentration of hydrogen ions in a 0.1M solution of H2SO4 is 0.2M.
To find the concentration of H2SO4, first calculate the number of moles of NaOH using the formula: moles = concentration x volume (in dm^3). Then, use the balanced equation to determine the mole ratio between NaOH and H2SO4. Finally, calculate the concentration of H2SO4 by dividing the moles of H2SO4 by the volume of H2SO4 used.
To standardize 1N H2SO4 with KHP, you would first prepare a solution of KHP of known concentration. Then, titrate the KHP solution with the 1N H2SO4 solution until the endpoint is reached. The volume of H2SO4 used in the titration can then be used to calculate the exact concentration of the H2SO4 solution.
The balanced chemical equation for the reaction is H2SO4 + 2NaOH -> Na2SO4 + 2H2O. From the mole ratio, 1 mole of H2SO4 reacts with 2 moles of NaOH. Using the volume and concentration of NaOH, we can calculate the moles of NaOH used. Then, knowing the moles of NaOH used and the volume of H2SO4, we can find the concentration of sulfuric acid.
To prepare 0.02N H2SO4 from 0.1N H2SO4, you can dilute the 0.1N H2SO4 by adding a calculated amount of water. To calculate the dilution factor, you can use the formula: C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration (0.02N), and you can solve for V2 to find the volume of the 0.1N H2SO4 to be diluted with water to get 0.02N H2SO4.
To prepare a 0.005 M solution of H2SO4 with pH 4, you can first calculate the concentration of H+ ions needed to achieve a pH of 4. Then, use the dissociation of H2SO4 to determine the amount of H2SO4 needed to provide that concentration of H+ ions. Finally, dilute the calculated amount of H2SO4 with water to reach the desired volume of the solution.
The reaction is:NaBr(s) + H2SO4(l) → HBr(g) + NaHSO4(s)
To determine the concentration of H2SO4 in titrations, a known concentration of a base (such as NaOH) is slowly added to a known volume of the acid solution until the equivalence point is reached. An indicator or a pH meter is used to determine the exact point of neutralization. By knowing the volume and concentration of the base added, the concentration of the H2SO4 can be calculated using stoichiometry.
To determine the concentration of the acid (H2SO4) in a titration, you will need to know the volume of the acid used, the volume of the base added, and the molarity of the base. By using the balanced chemical equation of the reaction and the volume of the acid and base used, you can calculate the concentration of the acid.
The pH of a 0.1 M solution of sulfuric acid (H2SO4) is around 1. Note that the pH of sulfuric acid solutions will vary depending on concentration.
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
