aqueous or solution in water
(aq) is the symbol for "aqueous".
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
You can make potassium chloride precipitate by adding silver nitrate (AgNO3). The chemical equation being AgNO3(aq)+ KCl(aq) = KNO3(aq) + AgCl(s) You know that silver nitrate will form a precipitate as you can see this on a solubility chart.
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.
'aq' , sometimes subscripted at the right of the element's symbol: eg. Na+aq
Barium chloride and sodium sulfate Molecular equation: BaCl2(aq) + Na2SO4(aq)--> BaSO4(s) + 2NaCl(aq) ionic equation: Ba+2(aq) + 2Cl-(aq) + 2Na+(aq) + SO4-2(aq) --> BaSO4(s) + 2Na+(aq) + 2Cl-(aq) Net ionic equation is Ba+2(aq) + SO4-2(aq) --> BaSO4(s)
(s)=solid and (aq)=aqueous also (g)=gas
The abbreviation (aq) means aqueous - suspended in or dissolved in water.
You would see the formation of a precipitate which would be lead chloride.Pb(NO3)2(aq) + 2NaCl(aq) --> 2NaNO3(aq) + PbCl2(s)
I am not sure what you mean, but if you mean like answer a chat question you will find it on the chat panel Well atually do you play AQW or AQ ?
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
HCl* Is Hydrogen Chloride and the (aq) simple means aqueous (solution in which water dissolves)
You go to the home page on aq world and the you scroll down then you will see guardian verification the you write in your user name password on both aq and aqwordls
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Do you mean chemical equation? 2AgNO3(aq) + K2SO4(aq) --> 2KNO3(aq) + Ag2SO4(s) This is an example of a double replacement/displacement reaction.
SO42-(aq) + Ca2+(aq) ---> CaSO4(s)
it will produce gaseous hydrogen sulfide and a sodium nitrate in a solution. see below Na2S(aq) + 2HNO3(aq) --> H2S(g) + 2NaNO3(aq)
NaH2PO4(aq) + H2OàH3PO4(aq) + NaOH(aq) H3PO4(aq)ßàH+(aq) + H2PO4_(aq) H2PO4-(aq)ßàH+(aq) + HPO42-(aq) HPO42-(aq)ßàH+(aq) + PO43-(aq)
