Preparing iron standards in dilute acid helps to prevent the oxidation of iron, which can lead to inaccurate results. The acid helps to stabilize the iron in its reduced form, ensuring that the concentration remains constant for accurate measurements. Additionally, the acid can also help to dissolve any non-iron impurities that may be present in the sample, allowing for a more accurate determination of the iron content.
To prepare 0.1N phosphoric acid, you can dilute a more concentrated phosphoric acid solution, such as 85% phosphoric acid, to achieve the desired concentration. Measure the volume of the concentrated acid needed based on the final volume you want to prepare, then dilute it with distilled water accordingly. Ensure to use appropriate safety precautions and equipment when working with acids.
To prepare a dilute acid solution from a concentrated acid, you can slowly add the concentrated acid to water while stirring. Never add water to concentrated acid as it can cause splattering. Always add acid to water to ensure proper mixing and to prevent violent reactions. Mix well after adding the acid to ensure uniform dilution.
To prepare 0.25N sulphuric acid from 2N sulphuric acid, you can dilute the 2N solution by adding 7 parts of water to 1 part of the 2N solution. This will result in a final 0.25N sulphuric acid solution.
A dilute acid is generally safer to handle compared to a concentrated acid. However, it can still cause skin and eye irritation, so proper safety precautions, such as wearing protective equipment and working in a well-ventilated area, are necessary when working with dilute acids.
The ratio of water to concentrated sulfuric acid in dilute sulfuric acid is typically 10:1, meaning there is about 10 times more water than concentrated sulfuric acid in the solution. This dilution is necessary to reduce the concentration of sulfuric acid for safety and handling purposes.

Metaphosphoric acid is often used as a moisture- or water-absorbing reagent. To prepare one-liter of 5 percent metaphosphoric acid, dilute 59 ml of 85 percent metaphosphoric acid with one liter of distilled water.
To prepare 4N dilute sulfuric acid, you would first calculate the volume of concentrated sulfuric acid needed based on its concentration. Then, slowly add the calculated volume of concentrated sulfuric acid to an appropriate volume of water while stirring continuously. Finally, dilute the solution to the desired volume with water and ensure proper mixing to obtain 4N dilute sulfuric acid for use in the experiment.
To prepare a 0.001 M HCl solution, you can dilute concentrated hydrochloric acid with water. Measure the appropriate volume of the concentrated acid and add it to a volumetric flask. Dilute with water to the desired volume, and make sure to mix well. Use proper safety equipment and handle the acid with care due to its corrosive nature.
Dilute acid is already a solution.
To prepare 0.25M sulfuric acid, you can dilute concentrated sulfuric acid (98%) by adding the appropriate amount of water to achieve the desired concentration. Measure out the required volume of concentrated sulfuric acid using a volumetric flask, then dilute with water while stirring until the final volume is reached. Remember to always add acid to water slowly and with good mixing to prevent splattering and heat generation.
