Water filters are used to remove chemical, physical and biological contaminants from water. By removing these contaminants, water filters improve the smell, taste and safety of water used for drinking, cooking and bathing. They are also used to aid in meeting public health standards for swimming poo
Filtered water is water that has been treated with a chemical or mechanical process to remove particles and pollutants. The exact components that are removed from the water vary with the filtration process.
Make a water filter by adding filtering material, such as pebbles, grass or cotton, to a large container. Next, add a layer of gravel and fill the rest of the container with sand. Finally, pour water through the filter and collect it at the bottom. Purify the water if required.
Ionic compounds are chemical compounds that are formed by an ionic bond, which means that two or more atoms combine by transferring or sharing one or more electrons. These compounds are also called electrovalent compounds. Ionic compounds include sodium chloride, sodium sulphide and sodium hydroxide
Ionic compounds dissolve in water because the hydrogen and oxygen atoms in the H2O molecules have partial charges that attract the ions in the solid compound, causing it to dissociate into separated ions. Differences in electronegativity account for the partial positive charge carried by water's hyd
Water filters work by disinfection methods, filtration, reverse osmosis, distillation and ion exchange to remove harmful impurities. Each process has its advantages and kills specific types of contaminates. Disinfection methods include using choline, boiling and pasteurization to kill bacteria that
An ionic bond is a type of chemical bond established between two atoms by the transfer of the valence electrons from one atom to another. This type of bond is also known as electrovalent or polar bond. Salts are a good example of substances made with ionic bonding.
Most ionic compounds are soluble in water because the electrostatic forces of the polar water molecules are stronger than the electrostatic forces keeping the ions together. There are several exceptions, however, where the electrostatic forces between the ions in an ionic compound are strong enough
Ionic compounds are formed by the electrostatic force of attraction between two oppositely charged ions, forming a neutral compound. Ions are formed when atoms either gain or lose electrons to obtain a stable electron configuration.
Non-ionic detergents are detergents that don't include any ionic group, carry any charge or react with hard water ions. These detergents also are called neutral detergents because they are made of equal strengths of acid and alkali, resulting in a pH value of 7.
