Which method is used to prepare insolubleinsoluble salts?
precipitatiprecipitationon
13
answer
eymmcl2003
Name the precipitate formed when barium nitrate solution and sodium sulphate solution
react together
Barium Barium sulphatesulphate
14
answer
eymmcl2003
NaOH + HNO3 NaNO3 + H2OIn a titration, 20cm3 of sodium hydroxide
was neutralised by 15cm3 of 0.2 mol/l nitric acid. Calculate the concentration of
the sodium hydroxide solution.
15
answerCVH+ (acid) = CVOH- (alkali)
0.2 x15x1 = Cx20x1
3= C x 20
C = 3/20 = 0.15 mol/l
