Ozone Reactions with Inorganic and Organic Compounds in Water

Iron removal. It is known that in neutral environment the passage from a reduced to an oxidized form is thermodynamically favorable. The ferrous iron is, therefore, easily oxidized by ozone by the following reactions: 2+ 3+OO32 HO2 2Fe 2Fe Fe(OH)3 ⎯⎯⎯→ ⎯⎯⎯→ →↓ (3) This reaction implies a consumption of 0.43 mg O3 mg-1 of Fe2+.

Unfortunately potassium dichromate(VI) solution turns green as you run it into the reaction, and there is no way you could possibly detect the color change when you have one drop of excess orange solution in a strongly colored green solution. With potassium dichromate(VI) solution you have to use a separate indior, known as a redox indior.

Reaction of iron with air. Iron metal reacts in moist air by oxidation to give a hydrated iron oxide. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner. Finely divided iron powder is pyrophoric, making it a fire risk.

Alkali metal - Wikipedia

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.

Reaction of Iron with Water: Reaction of iron with cold water is very slow and comes into notice after a long time. Iron forms rust (iron oxide) when reacts with moisture present in the atmosphere. Iron oxide and hydrogen gas are formed by passing of steam over iron metal. Other metals usually do not react with water or react very slowly.

Determination of Calcium, Magnesium, and Sodium by Atomic

iron requires a separate lamp (as do most elements) as well as a different operating wavelength. Iron is an interesting non-toxic surrogate for heavy metals, whose presence in drinking water supplies is an important public health issue. Atomic emission spectroscopy (AES) is a convenient method for the determination of alkali metals in water
