Sulphuric acids
H2SO4 is not metals. These two can go together and make H2.
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.
Together they make ammonium sulfate and water.
To prepare a 1N solution of sulfuric acid (H2SO4), you would need to dissolve 49 grams of H2SO4 in enough water to make 1 liter of solution. Since the density of sulfuric acid is around 1.84 g/ml, you would need approximately 26.6 ml of H2SO4 to make a 1N solution.
2koh + h2so4 = k2so4 + 2h20
9.62 Mol H2SO4 ( 6.022 X 10^23/1mol H2SO4 ) = 5.79 X 10^24 molecules of H2SO4
The ratio of H2SO4 to WHAT!
To make 4.5 M H2SO4 from concentrated sulfuric acid (98% H2SO4), you would need to dilute it with water. Calculate the volume of concentrated sulfuric acid needed based on the final volume desired, then add water to reach the total volume. Always remember to add acid to water slowly and carefully to avoid splashing or overheating.
You would need to react iron with sulfuric acid (H2SO4) to produce iron sulfate (FeSO4).
H2SO4 is sulfuric acid
To prepare 1N H2SO4 from 95% H2SO4, you would first need to dilute the 95% H2SO4 with water by adding the appropriate amount of water to achieve the desired concentration. To calculate the volume of 95% H2SO4 needed to make 1N solution, you need to use the formula: (Normality of stock solution) * (Volume of stock solution) = (Normality of diluted solution) * (Volume of diluted solution). Adjust the volumes accordingly to prepare the desired 1N solution.
Copper (II) sulphate, CuSO4 is prepared by mixing copper (II) oxide, CuO with sulfuric acid, H2SO4. CuO + H2SO4 --> CuSO4 + H2O
