What happens to the indicator when hydrochloric acid is added to sodium hydroxide?
It turns from its original blue colour to red.
What happens to sodium when added to hydrochloric acid?
NaCl salt is formed and H2 gas is given off
What happens if hydrochloric acid is added to copper 2 oxide?
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.
What happens to pH of water when hydrochloric acid is added to water?
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.
What make soluble in water will fizz when hydrochloric acid is added?
is soluble in water and will fizz when hydrochloric acid is added
What happens if phenolphthalein solution is added in hydrochloric acid?
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.
What happens when fizzy indigestion powder is added to water?
When fizzy indigestion powder is added to water, it typically reacts to produce carbon dioxide gas, which creates bubbles and fizzing. This reaction occurs because the powder contains ingredients like sodium bicarbonate that react with acids in the stomach or with water to neutralize acidity. The effervescence makes it easier to ingest the powder and can help relieve symptoms of indigestion by facilitating the release of gas and improving digestion.
What happens when dilute hydrochloric acid is added to magnesium?
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.
What happens when calcium metal is added to a dilute solution of hydrochloric acid?
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)
What happens when you add Cu to hydrochloric acid?
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.
What substance is soluble in water and will hissing when hydrochloric acid is added?
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
What is the color of the indicator when an excess of hydrochloric acid has been added?
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
