Acid + Insoluble solids (Metal / base / carbonates)

Soluble salts (non-sodium / potassium / ammonium salts are prepared using this method. Categorize the salts that can be prepared using acid reacts with insoluble substance method. prepared by acid + insoluble substance zinc nitrate copper(II) carbonate magnesium sulfate iron(II) chloride calcium chloride aluminium nitrate copper(II) sulfate zinc carbonate cannot be prepared by acid + insoluble substance method sodium sulfate silver chloride lead(II) sulfate ammonium carbonate lead(II) chloride calcium sulfate potassium carbonate Note: Not all metals are suitable to be used. Watch the video on the reaction between copper(II) oxide and sulfuric acid. Fill in the blanks for the steps of the reaction. 1) Add excess copper(II) oxide to a beaker of sulfuric acid.2) Stir to dissolve the copper(II) oxide until it can no longer dissolve to ensure the acid is used up.3) Filter to remove the excess copper(II) carbonate. The filtrate is copper(II) sulfate solution.4) Heat the filtrate in an evaporating dish until saturation.5) Allow it to cool down and crystallise. 6) Dry the salt crystals formed with filter papers. Why is an excess of solid added to the acid? To form a saturated solution. To use up all the acid.
