Sodium chromate can be prepared by oxidizing a chromium(iii)salt with sodium peroxide in alkaline solution.the chromium (iii) ions are oxidized to chromate ions.The peroxide ions are reduced to hydroxide ion.write down unbalanced half reaction equation for the reaction the physical state of all the reaction.The physical states of all the reagents and products must be shown throughout
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
