How do you test for hydrogen gas when zinc and hydrochloric acid are mixed?

As metal carbonates react with acid, a neutralisation reaction happens. Salt, water, and carbon dioxide are produced. This can be expressed in the following general equation:
metal carbonate + acid → salt + water + carbon dioxide
To test for carbon dioxide the gas can be bubbled through limewater. Carbon dioxide will dissolve slightly in water to make a weak acid (carbonic acid). Another neutralisation reaction then happens between the limewater (calcium hydroxide) and the carbonic acid. This makes the limewater turn milky, which is the positive result for carbon dioxide.

What Gas produced when metals react with dilute hydrochloric acid?
Hydrogen gas. This can be tested via the 'pop' test.
How do you test hydrochloric acid and magnesium metal?
you put the hydrochloric acid in a test tube then you put the magnesium metal in the test tube with the hydrochloric acid in it then you put a cork on the top ofthe test tube and watch it fizz.
Which acid you need to use for gold test hydrochloric acid and sulfuric acid?
nitric acid
Why do you add hydrochloric acid to test for sulphate?
you do it for cabonates
Which gas is evolved when hydrochloric acid is added over a piece of marble in one test tube and on zinc granules in the second test tube?
Zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2), a salt and hydrogen gas (H2). Marble is primarily composed of calcium carbonate (CaCO3) which reacts with hydrochloric acid (HCl) to form Calcium Chloride (CaCl2) which is a salt, water (H2O), and carbon dioxide gas (CO2). The first test tube with water evolves carbon dioxide and the second test tube with zinc granules evolves hydrogen gas.
How to test the presence of the reaction of zinc and hydrochloric acid?
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.

Hydrogen gas. This can be tested via the 'pop' test.
How do you test hydrochloric acid and magnesium metal?
you put the hydrochloric acid in a test tube then you put the magnesium metal in the test tube with the hydrochloric acid in it then you put a cork on the top ofthe test tube and watch it fizz.
What is the symbol equation for the pop test for hydrogen?
That depends on what chemicals were mixed in order to produce the hydrogen gas. For example, if it was the metal magnesium (Mg), and the acid hydrochloric acid (HCl), then the equation would be Mg(s) + 2HCl(aq) -- > MgCl2(aq) + H2(g). Please note that the 2 after MgCl is supposed to be a subscript, as is the 2 after hydrogen. We are having difficulties with the subscripts and superscripts right now.
How does copper react in hydrochloric acid?
it makes the water go cloudy but when it comes to doing the hydrogen test it doesn't do anything
When hydrogen chloride is dissolved in water to form hydrochloric acid what happens to the hydrogen chloride?
when hydrogen chloride is dissolved in water to form hydrochloric acid, the hydrogen chloride turns to HCL subscript 38 because of the water molecules. i also believe that they change from clear to a misty green colour but it may just be the result of a dirty test tube.
What happens when a piece of Mg ribbon is place in a test tube with Hydrochloric acid and cover the mouth of the test tube?
Metal + Acid --> Salt + Hydrogen Gas. As a result, the end product of this reaction is magnesium chloride and hydrogen gas. Covering the mouth of the test tube simply prevents the hydrogen gas from escaping, and allows you to test for its presence by using a lighted splint.
What is the best way to create hydrogen?
Mix Hydrochloric acid with strips of magnesium and catch the resulting gas using a balloon over a test tube

nitric acid

How can you collect hydrogen coming from a chemical reaction of magnesium ribbon and hydrochloric acid?
First of all, place bits of the magnesium into a test tube. Then pour the acid into the tube, in the meantime locking the tube with a balloon. Tighten it up and theres your stored hydrogen :)
