Caib 4: Meascán A Dheighilt, Tuaslagáin Agus Meascáin Flashcards
Meascán
Dhá nó níos mó substaint nach bhfuil cuingrithe (combined) go ceimiceach.
Mixture
Two or more substances not chemically combined.
Tuaslagán
Meascán speisialta ina bhfuil substaint tuaslagaithe i substaint eile. Is meascán foirfe é.
Solution
Special mixture containing a substance dissolved in another substance. It is a perfect combination.
Samplaí de tuaslagáin:
Salann in uisce
Siúcra in uisce
Alcól in uisce
Examples of solutions:
Salt in water
Sugar in water
Alcohol in water
Meascán nach tuaslagáin iad:
Ola agus uisce
Gaineamh agus uisce
Plúr agus uisce
Non-solvent mixture:
Oil and water
Sand and water
Flour and water
Tuaslagán
Meascán de tuaslagáit i dtuaslagóir.
Solution
Mixture of a solute in a solvent.
Tuaslagáit
An solad curtha sa leacht
Solute
The solid put in liquid
Tuaslagóir
An leacht ina bhfuil tuaslagáit ag dul isteach.
Solvent
The liquid that the solute is going into.
Tuaslagann Tuaslagáit i dTuaslaglóir chun Tuaslagán a dhéanamh.
Dissolve Solute in Solvent to make a Solution.

Intuaslagthacht
Inthuaslagtha: Nuair a thuaslagann rud i rud eile. Mar shampla, tá salann intuaslagtha in uisce.
Dothuaslagtha: Nuair nach dtuaslagann rud i rud eile
Mar shampla ta gaineamh dothuaslagtha in uisce
Solubility
Soluble: When something dissolves in something else. For example, salt is soluble in water.
Insoluble: When something doesn’t dissolve in something else. For example sand is insoluble in water.
Fuaidreán
Meascán de cháithníní beaga ar fud leachta, nach bhfuil siad tuaslagtha.
Suspension
A mixture of small particles throughout a liquid, which are not dissolved.
Tuaslagán Fuaidreán
I dtuaslagáin, tuaslagann na I bhfuaidreán, ní scarann na
cáithníní agus scarann siad cáithníní agus fanann siad mar
go hiomlán ón a chéile. píosaí beaga solaid ar snámh sa
Bíonn tuaslagáin glan/soiléir leacht.
mar is meascán foirfe iad. Bíonn fuaidreán modartha/neamhghlan
Mar tá solaid fós ann.
Solution Suspension
In solutions, the particles In a suspension, the particles do
dissolve and separate completely not separate and remain as small
from each other. Solutions are pieces solids floating in the liquid.
clean / clear as they are a Suspension is cloudy / unclean
perfect blend. because solids are still there.
Scagachán
Úsáidtear an modh seo chun rudaí a dheighlt nach bhfuil tuaslagtha (fuaidreán). Tá scagachán úsáidte chun cáithníní a bhaint ón aer, chun uisce a ghlanadh, agus chun caifé agus pasta a dhéanamh. Ligeann an scagaire rudaí áirithe dul tríd, ach ní ligeann sé rudaí eile. Usáidtear scagachán nuair nach bhfuil an meascán tuaslagtha
Filtration
This method is used to separate things that are not dissolved (suspension). Filtration is used to remove particles from the air, to purify water, and to make coffee and pasta. The filter allows certain objects to pass through, but does not allow other objects. Filtration is used when the mixture is not dissolved
Ag deighilt tuaslagán: Galú
Ba chóir dúinn féachaint ar na difríochtaí idir an tuaslagáit agus an tuaslagóir.
Mar shampla uisce agus salann. Cén teocht a leánn siad nó a ghalaíonn siad?
Beiríonn salainn ag 1413°C
Beiríonn uisce ag 100°C
Ní gá chun an meascán a bheiriú, ach is féidir linn é a ghalú chun é a dheighilt.
Separating solution: Evaporation
We should look at the differences between the solvent and the solvent.
Such as water and salt. At what temperature do they melt or evaporate?
Salt precipitates at 1413 ° C
Water boils at 100 ° C
It is not necessary to boil the mixture, but we can evaporate it to separate it.
Driogadh
Tá driogadh úsáidte chun meascáin (tuaslagáin de ghnáth) a dheighilt, ach chun an leacht a choimeád. Úsáidtear driogadh chun tuaslagán a dheidhilt agus an leacht a choimeád, nó meascán dhá leacht
Distillation
Distillation is used to separate mixtures (usually solutions), but to retain the liquid. Distillation is used to separate a solution and retain the liquid, or a mixture of two liquids
