How can you tell if a precipitate forms when you mix two solutions?

Answer 1

You will see solid material accummulate at the bottom of the reaction vessel.

e.g.

Mix barium nitrate ( a clear solution) , with copper sulphate solution (blue) ' a White solid of Barium sulphate will appear at the bottom of the reaction vessel. The copper nitrate solution will remain blue/green.

Ba(NO3)2(aq) + CuSO4(aq) = BaSO4(s) + Ch(NO3)2(aq)

Answer 2

You can tell if a precipitate forms when mixing two solutions by observing the appearance of a solid that settles at the bottom of the container. This solid is the precipitate formed from the reaction between the two solutions. Any change in color or cloudiness in the solution can also indicate the formation of a precipitate.

Answer 3

A precipitate is when two ions that mix together in a solution are then insoluble when they bind together in the solution (ususally water). If a precipitate will form is governed mostly by solubility rules that can be looked up.

Answer 4

Answer key:

The key to predicting precipitation reactions is to understand that only insoluble compounds form precipitates. In a precipitation reaction, two solutions containing soluble compounds combine and an insoluble compound precipitates.

Answer 5

Any chemical reaction which forms substances that are insoluble in water or only moderately soluble in water under certain conditions will form precipitates.

Some examples of substances that will precipitate out are:

- silver acetate

- silver chloride, silver bromide, silver iodide

- Mercury chloride, mercury bromide, mercury iodide

- lead chloride, lead bromide, lead iodide

- barium sulfate

- strontium sulfate

- lead sulfate

Answer 6

temperature change - heating the precipitate up and cooling it down?

Answer 7

when it is insoluble based on the solubility rules

Answer 8

A precipitate is a solid that forms when two solutions are combined.

Answer 9

When the product of the reaction is cloudy/ milky. Or there's a solid formed.
