Lime Softening 1 Lime Softening . Chemical precipitation is one of the more common methods used to soften water. Chemicals normally used are lime (calcium hydroxide, Ca(OH) 2) and soda ash (sodium carbonate, Na 2CO 3). Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause non-carbonate ...

A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, or chemicals affect the rate of respiration. Respirometers are designed to measure respiration either on the level of a whole animal or plant or on the cellular level.

Glass cullet from the crushing of post-consumer glass is readily available in urban areas. It can be added in small quantities (probably < 20%) into many mixes, but its smooth surface means that it is difficult to achieve a good bond with the surface. Glass dust is a hazardous irritant, so appropriate health and safety precautions must be taken (see Section 7.4.3).
