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.

Can concentrated nitric acid be used in flame test instead of concentrated hydrochloric acid?
Cleaning of the test wire (platinum or nickel-chromium alloy) may by realized with nitric acid or hydrochloric acid.Rinsing is made with demineralized water.
What is Lucas reagent?
This is a mixture of concentrated hydrochloric acid and anhydrous zinc chloride (which acts as a catalyst). To prepare, mix 136.29 g of anhydrous zinc chloride (ZnCl2) with 105 g of concentrated hydrochloric acid (HCl). Place beaker in an ice bath, due to the exothermic reaction. Stir with a glass rod until all ZnCl2 is dissolved.
Placing a drop of vinegar on a mineral is a test for .?
acid reaction
What is the name of the amino acid responsible for Hopkins-cole reaction test what is the formula of this amino acid?
Tryptophan.
What is the triiodomethane reaction of phenol?
The triiodomethane (iodoform) reaction of phenol involves the conversion of phenol to iodoform in the presence of iodine and sodium hydroxide. The reaction proceeds through oxidation of phenol to benzoic acid, followed by further oxidation and degradation to iodoform. This reaction is commonly used as a test for the presence of a methyl group attached to a phenolic compound.
A strip of zinc is dropped into a test tube of hydrochloric acid?
an exothermic reaction
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.
Name the element produced when magnesium and metal reacts with hydrochloric acid and how could you test for the presence of this element?
Mg HO + Cl
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.
How do you test hydrochloric acid?
Blue litmus paper would turn red indicating it as an acid. Addition to silver nitrate would result in a white precipitate of silver chloride indicating the presence of chloride. These two tests would show the substance to be hydrochloric acid.
Lucas reagent is used to test what homologous series?
Lucas reagent is used to test for the presence of alcohols in a substance. It is made from anhydrous zinc chloride and concentrated hydrochloric acid.
Which acid you need to use for gold test hydrochloric acid and sulfuric acid?
nitric acid
How can you test if limestone and marble are the same mineral?
Put a few drops of dilute hydrochloric acid on both samples. Both will fizz indicating the presence of calcite.
Why do you add hydrochloric acid to test for sulphate?
you do it for cabonates
Is the reaction between copper sulphate and hydrochloric acid endothermic?
If the test tube containing the reactants mixture became hotter then it is exothermic, and if it became colder then it is endothermic. You must do the reaction to know which is which!
Minerals that are will bubble when treated with hydrochloric acid?
Minerals that are carbonates will bubble when treated with hydrochloric acid. This is because carbonates contain the carbonate ion (CO3^2-), which reacts with hydrochloric acid to produce carbon dioxide gas and water. Here are some examples of carbonate minerals that will bubble with hydrochloric acid: Calcite (CaCO3) Dolomite (CaMg(CO3)2) Siderite (FeCO3) Aragonite (CaCO3) Rhodochrosite (MnCO3) The presence of carbonate minerals can be easily identified using this "acid test," which is a common practice used by geologists. When a drop of hydrochloric acid is placed on a carbonate mineral, a fizzing reaction will occur due to the release of carbon dioxide gas. Here is the chemical equation for the reaction between calcite and hydrochloric acid: CaCO3 (s) + 2HCl (aq) -> CaCl2 (aq) + CO2 (g) + H2O (l) It's important to note that not all minerals will react with hydrochloric acid. Only those that contain the carbonate ion will produce bubbles. Minerals that do not react with hydrochloric acid are referred to as "non-carbonates."
