Alum is not necessary for lilac-red hydrangeas. The color of hydrangea flowers is determined by the pH level of the soil. For lilac-red hydrangeas, the soil should be slightly acidic with a pH level of around 5.5 to 6.5. Adding alum to the soil can lower the pH level and help achieve the desired color, but it is not necessary if the soil already has the appropriate pH level. Regularly testing and adjusting the soil pH is the key to achieving the desired color for hydrangeas. **

The water runs out immediately on the Miele Novo Prima because there may be a blockage in the drainage system, preventing the water from being retained in the machine. This could be caused by a clog in the drain hose or filter, which needs to be cleaned or replaced. Additionally, there may be an issue with the water inlet valve not closing properly, leading to water continuously flowing out of the machine. It is important to troubleshoot and address these issues promptly to prevent further damage to the appliance. **

Alum belongs to the class of substances known as double salts. These salts are formed when two different salts are crystallized together, typically involving a combination of an alkali metal sulfate and an aluminum sulfate. Alum is commonly used in various industrial and household applications, including as a mordant in dyeing, in water purification, and in pickling. **

To make crystals using alum, start by creating a supersaturated solution of alum by dissolving alum powder in hot water. Stir the solution until no more alum can dissolve. Then, pour the solution into a clean container and suspend a seed crystal (a small piece of alum) in the solution using a string or fishing line. As the solution cools, the alum molecules will come together and form crystals around the seed crystal. After a few days, carefully remove the crystals from the solution and allow them to dry. **
