What is the objective of color changing milk of magnesia?
The objective of color-changing milk of magnesia is to show the pH level of a solution. By adding a color indicator that changes color at different pH levels to the milk of magnesia, you can visually see the acidity or alkalinity of the solution. This can help demonstrate concepts related to acids and bases.
What is the purpose of adding iodine solution to the onion cell?
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
Which causes the pH of a solution of a solution to increase?
Adding a base
What is the purpose of adding water to the base?
Adding water to a base can help to dissolve or dilute substances, adjust the pH level, increase the volume of the solution, or facilitate certain chemical reactions. It can also help to control the temperature during a reaction or to provide a medium for mixing and stirring.
What happens when the pH solution is lower?
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
What is the effect of adding sulfuric acid in iodimetry titration?
Adding sulfuric acid in iodimetry titration helps to oxidize iodide ions to iodine, which is then titrated with a standard solution of sodium thiosulfate. Sulfuric acid also prevents the interference of other reducing agents that may be present in the sample being tested.

What is the mole fraction of sulfuric acid in a solution made by adding 3.4 grams of sulfuric acid to 3500 mL of water?
The mole fraction must be calculated in moles solvent over moles solution. So, 3.4 grams sulfuric acid equals .0347 moles sulfuric acid. 3500 mL water equals 3500 g water equals 194 mols. .0347 mols/(.0347+194) = 1/5591.77 mols/mol
What is the purpose of adding sulfuric acid?
Sulfuric acid is commonly added to adjust the pH of solutions, such as in industrial processes, water treatment, and laboratory experiments. It is also used in the production of chemicals like fertilizers, detergents, and explosives.
What is the purpose of adding NaCl solution of soap?
Adding NaCl solution to soap mixture helps to precipitate out the soap, making it easier to separate from the rest of the solution. This process is known as salting out and helps concentrate the soap for further processing.
What is the effect of adding the sulfuric acid before KI in iodometric titration?
Adding sulfuric acid before KI in an iodometric titration helps to acidify the solution and prevent the premature oxidation of iodide ions to iodine. This ensures that the iodide ions react with the analyte (substance being tested) instead of being oxidized by any oxidizing agents present in the solution. Acidifying the solution also helps to stabilize the iodine formed during titration.
How is sulfuric acid neutralization typically carried out in industrial processes?
In industrial processes, sulfuric acid neutralization is typically carried out by adding a base, such as sodium hydroxide, to the acid solution. This reaction results in the formation of water and a salt, which is usually a sulfate compound. The pH of the solution is monitored and adjusted as needed to ensure complete neutralization.
Why do you add little sulphuric acid to copper sulphate solution during electroplating?
Adding a small amount of sulfuric acid to the copper sulfate solution during electroplating helps improve the conductivity of the solution. This allows for more efficient deposition of copper onto the object being plated. The sulfuric acid also helps to maintain the proper pH level of the solution, which is important for achieving a quality plating finish.
What happens when you mix sulphuric acid with distilled water?
When mixing sulfuric acid with distilled water, it generates heat. It is important to add acid to water slowly while stirring, as adding water to acid can cause a violent reaction. Diluting sulfuric acid with water results in a solution with lower concentration and is commonly done to prepare solutions for various applications.
What will happen if sulfuric acid is added with water?
Adding sulfuric acid to water is the recommended way of working to avoid accidents.
