Can Someone Explain The Answer From The Clue Given?

[Bertspa]

1d) Divers always covered with a lot of NaCI? (7)

I take the answer to be "Several" but why? 

[bhg481]

divers can mean several

s + ever al(t)

[Atheist]

ever, with sal outside it.

S ever al

Sal = salt (Sodium Chloride)

[Buenchico]

ever (always)
inside
Sal (= a lot of salt, sodium chloride)

[Lie-in King]

Several (divers; diverse) - 'ever' (always, covered with) 'sal(t; NaCl; sodium chloride)'

[Atheist]

Sal = a lot of Salt (i.e. the first three letters.

 

[miser]

s ever al - 'sal' another name for salt

divers - some, several

Many thanks for that. When I googled NaCI, the only response I got was, The National Advisory Committee on Immunization.

^^^ That's because you've misread a small 'l' as a capital 'I'!

Sodium chloride = NaCl .

[Lie-in King]

I said that 😉
