| Pb(NO3)2; NaNO3; KNO3 ALL are soluble because | all nitrates are soluble |
| PbCl2; NaNO3; KNO3 one is insol it's ... | PbCl2 |
| All nitrates are | soluble |
| LiCl; NaNO3; KNO3 are all soluble because | all alkali metal compounds are soluble |
| If an insoluble compound is formed in a reaction | a precipitate is formed |
| When lead nitrate and sodium iodide solutions are mixed a yellow ppt forms; it's ... | lead iodide |
| NaOH(aq) + FeSO4(aq) a ppt forms - it's | Fe(OH)2 |
| NaOH(aq) + FeSO4(aq) a ppt forms - it's colour is | green |
| Na2CO3; CuCO3; K2CO3 - one is insoluble it's | CuCO3 |
| NaI(aq) + Pb(NO3)2(aq) a ppt forms - it can be separated by | filtration |
| We can get pure CuSO4(s) from CuSO4(aq) by | crystallisation |
| Silver nitrate(aq) + KC(aq) gives a white ppt it's | silver chloride |
| PbCl2; AgCl; NaCl - the one that's soluble is | NaCl |
| NaOH(aq) + CuSO4(aq) a ppt forms - it's | Cu(OH)2 |
| NaOH(aq) + CuSO4(aq) a ppt forms - its colour is | blue |
| To get a pure insoluble salt it needs to be | filtered, washed with water & then dried |
| Pb(NO3)2(aq) + NaCl(aq) the ppt will contain impurities such as | NaNO3 |
| iron III sulphate (aq) + NaOH(aq) ppt formed is | iron III hydroxide |
| iron III sulphate (aq) + NaOH(aq) ppt formed is coloured | brown |
| add HCl to NaCl(aq); KNO3(aq); Pb(NO3)2 (aq) - one gives a ppt it's.. | Pb(NO3)2 (aq) |
