Why do you have to filter the mixture?
To get rid of any residue that is left behind. Eg) a mixture of water and sand. You filter the sand because you only want the water.
How can you separate barium sulphate from a mixture of barium sulphate and water?
Dissolve the Barium Chloride in cold water, cold because the Calcium Sulfate is slightly soluble in water and the cold water will prevent it from being dissolved, then filter out the Calcium Sulfate.
When you evaporate the ink why water left behind?
The dye and other additives remain as a residue.
When mineral rich water evaporates it leaves behind?
A residue formed from salts remain.
When mixing powder paint and water then boiling that water what is left behind?
The residue is the paint powder.

How do you separate a mixture of charcoal from salt?
put this mixture in water. salt will dissolve in water. now filter this solution with a filter paper. we will get particles of charcoal on the filter paper as residue. now heat the solution of salt and water .the water will evaporate leaving behind salt. thus the mixture of charcoal and salt is separated.
When you evaporate the ink why water left behind?
The dye and other additives remain as a residue.
What is the liquid that run through filter paper called?
The filtrate.
Name the substance on heating leaves no residue behind?
Ammonium nitrate leaves no residue when heated:NH4NO3 Δ→ N2O + 2H2O
You are given a mixture of sulfur potassium nitrate and carbon and asked to separate the components so you end up with a pile of solid sulfur a pile of solid potassium nitrate a pile of solid carbon?
So, you have a pile of gunpowder and you want to separate it. Right? Here's are some clues: Saltpeter (potassium nitrate) is soluble in water. Sulfur and carbon are not. Furthermore, sulfur is soluble in acetone but carbon is not. This assumes that you have pure carbon and not charcoal powder. Depending on the quality of the charcoal powder, it could be more or less soluble in different substances. But let's just take your teacher at his word: Carbon is carbon. If there is enough differential in particle size you could sift the mixture through a screen but that doesn't guarantee you'll get ALL the carbon, sulfur or saltpeter out of the mix. If the particles are all the same size that won't work at all. (OR) here is a better phrased answer: Answer: Gunpowder is a mixture of sulphur, charcoal and potassium nitrate (nitre). When water is added to the mixture potassium nitrate dissolves. The mixture is then filtered. The filtrate is potassium nitrate solution while the residue is a mixture of sulphur and charcoal. The filtrate is evaporated on a sand bath to obtain nitre back. When carbon disulphide is added to the residue, sulphur dissolves. When this mixture is filtered the filtrate is sulphur solution while the residue is charcoal. Leaving it open evaporates the sulphur solution. Carbon disulphide evaporates and sulphur crystals are left behind.
Does electrical tape leave residue?
It can, the cheaper electrical tapes leave more residue than the better quality brands such as 3M. The longer you leave it on the more residue it leaves behind.
What kind of residue does acetone leave behind?
pure acetone drys leaving no residue. if something was dissolved in the acetone however, whatever was dissolved will be left as a residue.
What is left behind when a solution is heated?
A solid insoluble residue remain after the evaporation of water.
How do you remove residue left behind by rubber bathroom mats?
wd-40
What happens to coffee water after it evaporates?
