Which flame is not suitable for heating in Bunsen burner and why?
The yellow flame because that is the safety flame
What type of flame should be used for heating solids?
a blue flame
Why should you stop heating the solution before the liquid has completely evaporated?
The reason one should stop heating the solution before the liquid has completely evaporated is because heat will continue to carry over even after it is removed from the flame. This means that the liquid will continue to evaporate for a little longer.

What is the colour of the flame for heating?
The flame should be very pale blue (almost invisible) for heating strongly. This is achieved by opening the air hole fully.
Why is a Bunsen burner not used for heating when the air hole is closed?
When the air hole is closed, the flame is a luminous flame. This flame is not ideal for heating for the following reasons: it is not as hot as the non-luminous flame it is very unstable it produces a lot of soot thus, only non-luminous flames (the blue one) is ideal for heating. :)
Why is the blue flame on the Bunsen burner used for heating?
It's hotter than the yellow flame.
What color flame test indicates the presence of calcium?
