Webions react with the chromate ions of the indicator, potassium chromate, to form a red-brown precipitate of silver chromate. 2 Ag+ (aq) + CrO 4 2– (aq) → Ag 2 CrO 4(s) This method can be used to determine the chloride ion concentration of water samples from many sources such as seawater, stream water, river water and estuary water. WebNickel and water: reaction mechanisms, environmental impact and health effects. Seawater contains approximately 0.5-2 ppb of nickel, and rivers contain approximately 0.3 ppb. Phytoplankton contains 1-10 ppm nickel (dry mass), resulting in a 10 3 -10 4 bioconcentration factor compared to seawater. Bentic algae can be found both in …

Aluminium and Sodium Hydroxide Reaction Al + NaOH

WebAg, Au, Pt, Hg. The most active metals are so reactive that they readily combine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found … WebMetals such as lead, copper, silver and gold do not react with water because these metals are inert towards cold and hot water.
