Question

1. fill in the table with each hydrated ionic compound

formula
scf₂·3h₂o
mgso₄·8h₂o
cu(iii)so₄·5h₂o
name
calcium bromide tetrahydrate
sodium nitrate dihydrate
chromium(iii) oxide nonahydrate

Explanation:

Step1: Identify naming rules for hydrated ionic compounds

Name the cation first, then the anion, and end with the prefix -hydrate indicating the number of water molecules.

Step2: Name Cu(III)SO₄·5H₂O

Copper(III) sulfate pentahydrate

Step3: Name MgSO₄·8H₂O

Magnesium sulfate octahydrate

Step4: Name ScF₂·3H₂O

Scandium(II) fluoride trihydrate

Step5: Write formula for Chromium(III) Oxide Nonahydrate

Cr₂O₃·9H₂O

Step6: Write formula for Sodium Nitrate Dihydrate

NaNO₃·2H₂O

Step7: Write formula for Calcium Bromide Tetrahydrate

CaBr₂·4H₂O

Answer:

Formula	Name
MgSO₄·8H₂O	Magnesium sulfate octahydrate
ScF₂·3H₂O	Scandium(II) fluoride trihydrate
Cr₂O₃·9H₂O	Chromium(III) oxide nonahydrate
NaNO₃·2H₂O	Sodium nitrate dihydrate
CaBr₂·4H₂O	Calcium bromide tetrahydrate
