it gives us colour less form
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
Sodium.
By knowing or learning that the bright yellow lines observed with sodium chloride occur with all other compounds of sodium but not with any other compound of chlorine that does not contain sodium.
Sodium
sodium carbonate + copper sulfate ===> copper carbonate (s) + sodium sulfateNa2CO3(aq) + CuSO4(aq) ===> CuCO3(s) + Na2SO4(aq)
sodium thiosulphate
clear and colourless
anyone answer?
Sodium hydrogen sulphite: Sodium bisulfite, not sodium "meta" bisulfite
sodium and sulphur a think?? check a website or sumfin or ask albert einstein?? he'll no :)
As sodium sulfite (Na2SO4) dissolves, it dissociates into its ions: Na2SO4 --> 2Na+ + SO32-
Sodium sulphite is the IUPAC name. Its formula is Na2SO3 (NB there are only 3 oxygens in sulfite.
reaction betwen sodiumbisulphite and hydrogen peroxide
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
Because sodium is not as stable as copper.
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
Na2SO3 + H2SO4= Na2SO4 + SO2 + H2)
