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.

How can you prepare H2SO4 0.25N?
To prepare a 0.25N solution of H2SO4, you would need to dilute concentrated sulfuric acid (typically around 95-98% purity) with water. For example, to prepare 1L of 0.25N H2SO4, you would mix 20.6mL of concentrated H2SO4 with approximately 980mL of water. Always add acid to water slowly and carefully while stirring to avoid splashing and heat generation.
How many distilled water will be added to prepare 1000 ml 95 percent ethanol from 1000 ml 99 percent ethanol?
1. Extract 959,6 mL from the 99 % solution. 2. Add 40,4 mL water.
How do you prepare 6 N sulfuric acid?
To prepare 6N sulfuric acid, you would need to dilute concentrated sulfuric acid (typically around 96% purity) with distilled water while carefully monitoring the concentration using a calibrated pH meter or titration. The formula to calculate the dilution factor is: N1V1 = N2V2, where N1 is the initial concentration, V1 is the volume of the initial concentration you are using, N2 is the desired concentration, and V2 is the final volume you need to reach.
