The Homestake experiment was followed by other experiments with the same purpose, such as Kamiokande in Japan, SAGE in the former Soviet Union, GALLEX in Italy, Super Kamiokande, also in Japan, and SNO (Sudbury Neutrino Observatory) in Ontario, Canada. SNO was the first detector able to detect neutrino oscillation, solving the solar neutrino ...
Another earlier process to produce chlorine was to heat brine with acid and manganese dioxide. 2 NaCl + 2H 2 SO 4 + MnO 2 → Na 2 SO 4 + MnSO 4 + 2 H 2 O + Cl 2. Using this process, chemist Carl Wilhelm Scheele was the first to isolate chlorine in a laboratory. The manganese can be recovered by the Weldon process. [11]
Fill the tank completely with clean water, close the lid and leave to stand for 24 hours. [16] Flush: After the chlorine solution has sat in the tank for 24 hours, flush out/empty the storage tank. Do not drain the tank into a septic system or adjacent surface water body.
Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. This problem is avoided by the use of sodium hypochlorite, which is a relatively inexpensive solution used in household bleach that releases free chlorine when dissolved in water ...
Checking chlorine level of the local water source in La Paz, Honduras. Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water . This method is used to kill bacteria, viruses and other microbes in water.
Although of no commercial importance, potassium manganate can be oxidized by chlorine or by disproportionation under acidic conditions. [69] The chlorine oxidation reaction is 2 K 2 MnO 4 + Cl 2 → 2 KMnO 4 + 2 KCl. and the acid-induced disproportionation reaction may be written as 3 K 2 MnO 4 + 4 HCl → 2 KMnO 4 + MnO 2 + 2 H 2 O + 4 KCl
The length and breadth of the tanks are determined by the flow rate desired for the filters, which typically have a loading rate of 200–400 litres (0.20–0.40 m 3) per square metre per hour. Slow sand filters differ from all other filters used to treat drinking water in that they work by using a complex biofilm that grows naturally on the ...
HAWC August 14, 2014 HAWC with the Pico de Orizaba in the background, August 2014. The High Altitude Water Cherenkov Experiment or High Altitude Water Cherenkov Observatory (also known as HAWC) is a gamma-ray and cosmic ray observatory located on the flanks of the Sierra Negra volcano in the Mexican state of Puebla at an altitude of 4100 meters, at
