a mixture consists of two solids,sodium chloride and lead2 oxide
which of the following methodes can be used to removed the sodium chloride
from the mixture?
A.add water to the mixture and then filter
B.add conH2SO4 to the mixture and then filter
C.add dilute HNO3 to the mixture and then filter
D.add dilute NaOH solution to the mixture and then filter
我知a一定岩因為Pb0 is insoluble但我唔知d點解唔岩~d果果NAOH唔係會react with
PbO to form Pb(OH)2 insoluble?
如果唔係咁d果條式點write定冇reaction~解釋~唔該
