An explosion over 9000 times as powerful as a nuclear bomb. Please do not try unless you are in fume cupboard
It turns from its original blue colour to red.
NaCl salt is formed and H2 gas is given off
When hydrochloric acid is added to copper (II) oxide, a reaction takes place where copper (II) chloride and water are formed. The equation for this reaction is: CuO + 2HCl → CuCl2 + H2O.
The pH of water decreases when hydrochloric acid is added to it because hydrochloric acid is a strong acid that donates protons in water, increasing the concentration of hydrogen ions and lowering the pH of the solution.
is soluble in water and will fizz when hydrochloric acid is added
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
When calcium metal is added to a dilute solution of hydrochloric acid, a chemical reaction takes place in which calcium reacts with hydrochloric acid to produce calcium chloride and hydrogen gas. The balanced chemical equation is: Ca (s) + 2HCl (aq) -> CaCl2 (aq) + H2 (g)
When dilute hydrochloric acid is added to magnesium, a chemical reaction occurs where hydrogen gas is produced and magnesium chloride is formed as a product. The reaction can be represented by the equation: Mg + 2HCl -> MgCl2 + H2.
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
When copper (Cu) is added to hydrochloric acid (HCl), a chemical reaction occurs where the copper reacts with the hydrochloric acid to form copper chloride (CuCl2) and hydrogen gas (H2). This reaction is represented by the following equation: 2HCl + Cu -> CuCl2 + H2.
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
