Two Way Switch-Switches which can be used in pairs so that either can switch a light on or off. Each switch has terminals allowing them to be linked using Three Core and Earth cable. Voltage (V) - The numerical value of the electrical potential between two points in a circuit.Volts = Wattage/Amperes.lectrical Second Fix-Generally used to refer to that part of an electrical installation that is visible on completion-i.e. the light fitting, wall switches etc. Frequency-In alternating current, the rate at which the current changes direction-in the UK typically 50 Hertz.
To make bleach, a direct electrical current is sent through a sodium chloride solution (table salt and water). This basically splits the atoms leaving chlorine and the caustic soda. Both chlorine and caustic soda (lye) are extremely dangerous. These two chemicals are reacted together to create what we know as bleach.
1. bleaching agent-an agent that makes things white or colorless. blanching agent, whitener, bleach. benzoyl peroxide-a white crystalline peroxide used in bleaching (flour or oils or fats) and as a catalyst for free radical reactions.agent-a substance that exerts some force or effect.bleaching powder, chloride of lime, chlorinated lime-a white powder comprised of calcium hydroxide and chloride and hypochlorite and used to bleach and/or disinfect. bleach liquor-a solution containing bleaching agents that is used to bleach textiles or paper pulp.alcium hypochlorite-any hypochlorite of calcium; used as a bleaching agent. chlorine dioxide-an explosive gas (ClO2) used chiefly in bleaching paper or starch or soap or flour and in water purification. chlorine water-an aqueous solution of chlorine used as a bleaching agent.
