julie carried out a chemical reaction using magnesium and an acid the products of the reaction were magnesium chloride and hydrogen.
julie collected a test tube of the hydrogen.
describe what she should do to show that it was hydrogen.
when you burn/ignite hydrogen in a test tube, it should produce a "popping" sound~
hope this helps~ :)
thankyou jai
To show that the gas collected by Julie is hydrogen, she can perform a few simple tests. Here's what she can do:
1. Ignition Test: Julie can attach a small piece of cotton wool to the end of a thin wire. She should then dip the cotton wool into the collected gas and gently bring it near a flame or a Bunsen burner. If the gas is hydrogen, it will burn with a squeaky pop sound and produce a pale blue flame.
2. Test with a Lighted Splint: Julie can also perform the classic "pop" test using a lighted splint. She should carefully insert a lighted splint into the test tube containing the collected gas. If the gas is hydrogen, it will ignite with a pop sound when exposed to the flame.
Both of these tests are commonly used to identify hydrogen gas due to its distinctive properties. It's important to note that these tests should be performed with caution and in a well-ventilated area to ensure safety.
