What is the hottest fire color?
white-blue
When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
Is MnCl2 aqueous?
MnCl2 is rose-colored deliquescent crystals that are very soluble in water,and melts at 650°C and boils at 1190°C. The tetrahedral form, MnCI2. 4H20 , melts at 58°C and loses its water at 198°C and is used as a catalyst in paints,dyes,pharmaceuticals, and fertilizers, and for various other purposes.
How hot does strontium chloride burn?
As with all compounds of strontium, this salt emits a bright red colour in flame, and is commonly used in fireworks to that effect. Its chemical properties are intermediate between those for barium chloride, which is more toxic, and calcium chloride….Strontium chloride.

What is strontium flame?
Strontium chloride imparts a bright red color to a flame. A scarlet-red color is imparted to the flame by strontium chloride. The color is brighter red than the lithium flame color. Metal ions combine with electrons in the flame and the metal atoms are raised to excited states because of the high flame temperature.
What color does rubidium give off when heated?
dark red
Most of the alkali metals glow with a characteristic color when placed in a flame; lithium is bright red, sodium gives off an intense yellow, potassium is violet, rubidium is a dark red, and cesium gives off blue light. These flame tests are useful for identifying the metals.
What color flame is potassium?
