What do you call the purple gas that fills the test tube when a few crystals of iodine is being heated inside a test tube?
This is also iodine, as a gas.
Why is KMnO4 not prepared using Hcl acid?
because it will be oxdised by KMnO4 and Cl(-1)- --> Cl2(0) cholorine gas has poison
Redox titrations of ferrous ion with KMnO4 why the HCl is not used in this reaction?
KMnO4 will oxidize the HCl to Cl2 gas, a potentially hazardous vapor.
What is the word equation for potassium permanganate when heated?
here is the rection... 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 3H2O + 2.5O2 (alkaline) and in other conditions... 6 KMnO4 + 9 H2SO4 → 6 MnSO4 + 3 K2SO4 + 9 H2O + 5 O3 The H2SO4/KMnO4 reaction can also produce the oily Mn2O7, which is unstable and can decompose explosively.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
It is probably because a part of the oxygen produced from the reaction of KmnO4 and HCl is used up in oxidising the HCl to Cl2 gas

Which gas is evolved when KMnO4 reacts with H2C2O4?
The evolved gas is carbon dioxide (CO2).

What happens to gas in a balloon when that gas is heated?
The gas will expand as it is heated.

What brown coloured gas evolveed when lead nitrate crystals are heated in adry test tube?
nitrogen di oxide
Why heated gas become lighter?
because..................................................................................................................... density of heated gas is lower than cooled gas.
