Remove calcium from pool surfaces without draining the …
Calcium scale is a common issue in concrete pools as many pebble based pool surfaces now use white cement instead of grey. However, white cement contains around 36% calcium hydroxide which contributes to the challenge of managing calcium.
Common Cell Culture Problems: Precipitates- …
Common Cell Culture Problems: Precipitates -- When contamination is ruled out, turbidity in cell culture media is often explained by the precipitation of metals, proteins, and other media components. Precipitates can be harmful to cell health, as they may alter media composition by removing nutrients and other desirable components by processes such as chelation.

How Water is Ionized by a Water Ionizer – Life Ionizers
How ionized alkaline (and acid) waters get their pH: The positively charged calcium and magnesium ions to pass through the merane and become concentrated at the negatively charged plates. Calcium and magnesium are alkaline earth metals, they are responsible for giving the alkaline water, made by a water ionizer, its alkaline pH.
Precipitating, not plating, ZnO + KOH back to Zn + KOH
15/3/2009· If you use zinc cyanide in the alkaline bath, the efficiency increases significantly, as it also does for acid zinc, but these are of no use to you. There is also a problem with potassium hydroxide, as it absorbs carbon dioxide from the atmosphere to form potassium carbonate - this will reduce the efficiency of the fuel cell and any recovery process.

Potassium | Podcast | Chemistry World
It was from this pure hydroxide that Davy first isolated the metal potassium.To do this he used the relatively new force of electricity. Almost twenty years earlier, the Italian physician Luigi Galvani noticed that when he touched the central nerve of a dead frog with a metal knife, the muscles in the frog''s leg violently contracted.
