Which Of The Following Should Be Broken Into Ions When Writing A Complete Ionic Equation Select All That Apply class=

Sagot :

Step 1 - How to tell whether a given substance is ionic or covalent

To decide whether a substance is ionic or covalent, we must look for metals in its formula. If the substance is composed of both metals and non metals, it is an ionic susbtance.

If it's, on the other hand, composed solely by non-metals, it is a covalent substance.

Covalent substances do not produce ions in aqueous solution. Therefore, they can't be "broken into ions".

Step 2 - Analysing the given substances

H2O --> composed of H and O; both non-metals, so covalent

LiF --> composed of a metal (Li) and a non-metal (F), so ionic

K3PO4 --> composed of a metal (K) and non-metals (P, O), so ionic

AgCl --> composed of a metal (Ag) and non-metal (Cl), so ionic

Step 3 - Answering the exercise

All substances except H2O should be broken into ions when writing a complete ionic equation.

Answer: all except H2O
