Answer» a acid type of fire extinguisher contains the following compounds -1. Sodium hydrogencarbonate solution.2. Solution of sulphuric acid.Working System -These two SOLUTIONS are present in the separate systems in the extinguisher. When we press the KNOB of this fire extinguisher, then both the sodium hydrogencarbonate and sulphuric acid COMES in contact with each other. This results in production of carbon dioxide gas which stops the burning of an object and thus the fire GETS EXTINGUISHED. |
