A chemical garden is a set of complex biological-looking structures created by mixing inorganic chemicals. This experiment in chemistry is usually performed by adding metal salts, such as copper sulfate or cobalt(II) chloride , to an aqueous solution of sodium silicate (otherwise known as waterglass).
The chemical garden (or silica garden) was first observed by Glauber and described by him in 1646. [4] In its original form, the chemical garden involved the introduction of ferrous chloride (FeCl 2) crystals into a solution of potassium silicate (K 2 SiO 3, water glass).
The water is released over the plant's roots and then runs back into the reservoir below in a constantly recirculating system. As with deep water culture, there is an airstone in the reservoir that pumps air into the water via a hose from outside the reservoir. The airstone helps add oxygen to the water.
A team has been able to successfully light an LED bulb using power generated from a chemical garden
Pure lime is soluble in water containing carbonic acid, a natural, weak acid which is a solution of carbon dioxide in water and acid rain so it will slowly wash away, but this characteristic also produces autogenous or self-healing process where the dissolved lime can flow into cracks in the material and be redeposited, automatically repairing ...
Plus, at-home sparkling water makers like Sodastream and the new Ninja Thirsti make a damn fine sparkling water that's up to your own specific standards (like with extra-quadruple bubbles or with ...
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate . Additional chemicals vary depending on the mineral source and may include calcium oxide .
Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
