What is the density of 40ml of saline solution in 50 ml beaker?
The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
What is the most appropriate piece of equipment to accurately measure 85 mL of water?
100mL of measuring cylinder is the most appropriate (more than beaker) piece of equipment to measure 85mL of water.

Why is the beaker coverd with watchglass when heating the combine solutions of barium chloride and sodium sulfate solution on a waterbath?
protect the heat effect from the sun
Which is better for heating beaker or a test tubeand why?
A beaker is better for heating compared to a test tube because it does not break up easily.
What is use for beaker in labaratory?
to contain/hold things, particularly liquid solutions. can also be used when heating a solution on a hotplate. gets used A LOT.
Container used for mixing or heating of chemical solution?
In a chemical plant it would be a blend tank or reactor. In a laboratory it would be a reaction flask or beaker
What is use of beaker?
A beaker (Berzelius or Erlenmeyer) is used for: - to contain a liquid, or powdered and granulated materials - to be the container for chemical experiments - to be the container for the dissolution of materials - to collect the solution from a distillation apparatus - to contain a substance to be titrated
How do you create a solution?
Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
What equipment for measuring liquids?
beaker
