@topic: so is CO neutral or acidic?

Neutral but Our chemistry teacher said we wont prefer it so to be on the safer side write other ones
Bt if a Q is Directly Pointing about the Nature of CO thn we will write it as Neutral Oxide

Describe how a pure dry sample of barium sulphate is prepared from aqueous barium nitrate ... ? [5 Marks]

Why B? I mean why Only Calcium and they say ppt was not seen

add barium nitrate and potassium sulfate. filter. wash residue with distilled water. heat in oven. dry in folds of filter paper

there is a word not used in the question that's why.

Each and everyone of others will either dissolve or form no ppt in excess of NaOH. except for Ca which remains insoluble and forms a PPT.
