what gas is made from hydrochloride and zinc?
Is it zinc chloride?
how to test for zinc chloride what experiment to do .
thanks i`m stuck on these questions . not very good at science!
Yes, the gas formed from the reaction between hydrochloric acid (HCl) and zinc (Zn) is indeed zinc chloride (ZnCl2). When hydrochloric acid reacts with zinc, hydrogen gas (H2) is also produced along with zinc chloride.
To test for the presence of zinc chloride, you can perform a simple experiment called the precipitation reaction. Here's how you can do it:
Materials needed:
1. A solution of zinc chloride
2. A solution of sodium hydroxide (NaOH)
Procedure:
1. Take a small amount of the solution of zinc chloride in a test tube.
2. Add a few drops of the solution of sodium hydroxide to the test tube.
3. Observe any changes in the solution.
4. If a white precipitate (solid) forms in the solution, it indicates the presence of zinc chloride.
Explanation:
The reaction between zinc chloride and sodium hydroxide forms a white insoluble compound called zinc hydroxide (Zn(OH)2). The formation of this white precipitate indicates the presence of zinc chloride.
Keep in mind that proper safety precautions should be followed when conducting any experiment. If you're unsure or lack experience in performing experiments, it's always best to seek guidance from a teacher or a professional.
