01 · Identification

What Nickel is

Nickel is a silvery metal and is odorless. Its molecular formula is Ni and its molecular weight is 58.693 g/mol. It boils at 2730 °C, melts at 1455 °C, is practically insoluble in water.

Under the GHS it carries the signal word Danger. It is classed as hazardous Air Pollutants (HAPs).

04 · Handling and storage

Storing and handling Nickel

Storage conditions

PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practicable to lab in which carcinogens are to be used, so that only small quantities required for ... expt need to be carried. Carcinogens should be kept in only one section of cupboard, an explosion proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. An inventory ... should be kept, showing quantity of carcinogen & date it was acquired ... Facilities for dispensing ... should be contiguous to storage area. /Chemical Carcinogens/

Reactivity

NICKEL is not highly reactive in bulk. A reducing agent. Reacts with (is corroded by) acids to generate flammable hydrogen. Burns when heated in oxygen. Incompatible with oxidizing agents such as oxidizing acids, ammonium nitrate, chlorine, potassium perchlorate, nitryl fluoride. Powdered nickel is much more reactive; can ignite in air [Bretherick 1979 p. 170-171].
