- Q8Name the salt in this reactionZinc SulphateZinc ChlorideZincWhen sulphuric acid reacts with metal, it always forms a salt that ends in sulphate30s
- Q9Give one safety precaution when adding metals to hydrochloric acid?Sit down while doing the practicalKeep bags on the tableWear gogglesKeep the Bunsen burner on a blue flame30s
- Q10From the picture which metal reacted the most with the acid?IronSilverCalciumCopper30s
- Q11The student said that copper did not react with the acid. From the picture how can you tell she is rightIt only produced a few bubblesNo bubbles were producedThe acid stayed the same colourThe metal stayed the same colour30s
