Can precipitation be used as a separation technique?
A solution is treated with a chemical which react with one of the components forming a precipitate; the separation is possible after this by filtration.
What is a precipitaion?
APEX: A compound that doesnt disolve in water
What do you see when limestone is heated very strongly?
simply it breaks out due to forming of carbon dioxide in the gaps if it takes place in an close atmosphere with high pressure than turns into marble.
How can someone predict what formation of a precipate in a chemical reaction will take place in the solution?
For solutions of ionic compounds in water, the formation of a precipitate can be predicted by noting the concentrations of each kind of ions present in the solution after it is prepared. If the solubility product constant of any possible ionic compound-forming combination of these ions is exceeded, a precipitate will eventually form. If not, no precipitate will form.
Why does lime water become clear if you stop blowing air into it?
a precipitate (aqueous -> solid) must be forming
What reacts with lime water forming a precipitate?
Carbon dioxide
Chemical weathering processes are particularly effective on limestone landscapes forming?
Chemical weathering processes are particularly effective on limestone landscapes forming because of carbonation. When rainwater combines with acid in the air, limestone is formed.
What are the four possible outcomes of mixing two chemicals in solution?
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction
What reacts with water to produce limestone caves?
Carbon dioxide dissolves in water forming carbonic acid H2CO3, a weak acid that slowly erodes the limestone.
What is calcite?
Calcite is a carbonate mineral with the chemical formula CaCO3, which is a major rock forming mineral, particularly of limestone.
Can precipitation be used as a separation technique?
A solution is treated with a chemical which react with one of the components forming a precipitate; the separation is possible after this by filtration.
Why does calcium carbonate lose mass if heated?
Limestone loses mass when heated because of a chemical change: the gas carbon dioxide (CO2) is released by a chemical process when the rock is heated. The heat turns some of the calcium carbonate of the limestone into calcium oxide (quicklime) and carbon dioxide.
How can a mineral be changed into a different type of mineral?
3 stages: 1st, dissolve 2nd, react with the desired result forming chemical 3rd, precipitate
Is limestone a solution?
No it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
What is it called when two solids or a solids and a liquid are put together?
its value changes ,get new substance and the product doesn't remain the same after chemical reaction
What is a precipitaion?
APEX: A compound that doesnt disolve in water
What do you see when limestone is heated very strongly?
simply it breaks out due to forming of carbon dioxide in the gaps if it takes place in an close atmosphere with high pressure than turns into marble.
