Flame tests using metal salts | Resource | RSC Eduion

This is because the calcium ethanoate is relatively insoluble in ethanol, as opposed to water, so it precipitates as an inflammable solid, a firelighter that burns with a very clear flame so that any colour given to the flame is due to the metal ion in the salt solution. When a metal salt solution is sprayed onto the flame the electrons in the metal are excited and jump from one electron shell level to the next …

Fire extinguisher types: How to choose the right class

26/04/2017· They can also be used on Class A and some can be used on Class B fires. They consist of a pressurised solution of alkali salts in water, which, when operated, creates a fine mist, cooling the flames and preventing splashing. More expensive than some others, they cost around £35 for 2-litre, £70 for 3-litre and £110 for 6-litre sizes.
