Q.Give the systematic names for the following

Step 1. (i) Milk of magnesia is the common name for a suspension of magnesium hydroxide, Mg(OH)₂, in water (the alkaline earth analogue of 'milk of lime').

Step 2. (ii) Lye is a traditional common name for sodium hydroxide, NaOH.

Step 3. (iii) Lime, in this context, refers to (quick) lime -- calcium oxide, CaO, as covered in Section 5.6.1.

Step 4. (iv) Caustic potash is the common name for potassium hydroxide, KOH, the group-1 analogue of caustic soda (NaOH).

Step 5. (v) Washing soda is sodium carbonate crystallised as the decahydrate, Na₂CO₃·10H₂O, as covered in Section 5.3.1.

Step 6. (vi) Soda ash is the fully anhydrous form of sodium carbonate, Na₂CO₃, obtained once washing soda has lost all its water of crystallisation above 373 K. …

Match each common/trade name to its systematic chemical name and formula, drawing on the sodium-compound chemistry of Section 5.3.1 plus the gen …

• Confusing 'lye' (sodium hydroxide) with 'lime' (calcium oxide) -- both are traditional common names for caustic industrial alkalis but refer to compounds of two different metals. …
