"Once the material is moved from the stock bottle,it should not be returned into the bottle.This prevents contaminating the source" I didn't get the last line. Can anyone explain please!!!
I'm pretty sure that once a chemical is taken out of its container, there is a risk of the substance being affected by dust particles and bacteria in the air. Which is why you must use fresh samples when instigating a reaction!
Some chemicals can be dangerous and it can have a reaction with the pan or even seep through it, destroying the machine. If it is kept in a way boat, it can melt the material and cause a hazard.
my science teacher is making us watch this

Why is it advisable not to place chemicals on the pan of the balance?

@iwrsiyanawar1289 can the solids be transferred outside the scale to avoid spilling the solid on the scale?
Is it also called digital balance?
