Analysis RQP- chemical tests to identify the ions in unknown single ionic compounds

Question 1

aims

Answer 1

To identify the ions in unknown salts, using the tests for the specified positive and negative anions.

Question 2

step 1

Answer 2

Carry out one or more tests on each salt. You may need to dissolve a sample of salt in a little distilled water if you are given solids, rather than solutions.

Question 3

step 2

Answer 3

Record your observations carefully. Repeat any tests that do not get clear results.

Question 4

what 5 tests can be used? (described in Analysis topic flashcards) (include if they test for positive or negative ions)

Answer 4

• flame tests for positive ions
• hydroxide precipitates tests for positive ions
• test for negative carbonate ions
• test for negative sulfate ions
• test for negative halid ions
