What else can I help you with?
What is the purpose of adding sulfuric acid solution to the sample of milk of magnesia?
Adding sulfuric acid to milk of magnesia helps to precipitate the magnesium hydroxide in the solution. This can be done to isolate magnesium for further analysis or to determine the concentration of magnesium in the sample.
What are 3 ways to prepare hydrogen?
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.
Is adding hydrochloric acid to magnesium ribbon a physical or chemical?
Adding hydrochloric acid to magnesium ribbon results in a chemical reaction. The magnesium reacts with the hydrochloric acid to produce magnesium chloride and hydrogen gas. This process involves the breaking and forming of chemical bonds, indicating a change in the substance's chemical identity. Thus, it is a chemical change rather than a physical one.
Is adding magnesium to acid a chemical change?
Yes, because the chemical structure is compromised
What salt is formed when magnesium hydroxide is neutralized by hydrochloric acid?
The salt formed when magnesium hydroxide is neutralized by hydrochloric acid is magnesium chloride (MgCl2). This is because the H+ ions from the hydrochloric acid replace the OH- ions from magnesium hydroxide, leading to the formation of magnesium chloride and water.
How will excess magnesium be removed from sulphuric acid during experiment'?
Excess magnesium in sulfuric acid can be removed by adding a dilute acid, such as hydrochloric acid, to convert the magnesium to soluble magnesium chloride, which can be filtered out. Alternatively, the solution can be allowed to stand so that any unreacted magnesium settles to the bottom, and the supernatant can be decanted.
Is adding HCI to Mg a chemical change?
Yes. Magnesium metal reacts in hydrochloric acid to form magnesium chloride and hydrogen gas.
What is the product of adding dilute hydrochloric acid to magnesium oxide?
MgO + 2HCl =MgCl2 +H2O
How do show that adding acid to the magnesium ribbon resulted in a chemical change?
Adding acid to magnesium ribbon results in a chemical change because it produces hydrogen gas and magnesium ions through a reaction. This change can be observed by the formation of bubbles (hydrogen gas) and the dissolution of the magnesium ribbon. Unlike physical changes, the original substances (magnesium and acid) are transformed into new products with different chemical properties. The reaction can be represented by the equation: Mg + 2HCl → MgCl₂ + H₂.
Is adding dilute hydrochloric acid to magnesium oxide an exothermic reaction?
Yes, the reaction between dilute hydrochloric acid and magnesium oxide is exothermic because it releases energy in the form of heat. It is a chemical reaction that results in the formation of magnesium chloride and water.
How tp prepare magnesium acetate?
To prepare magnesium acetate, you can react magnesium oxide or magnesium hydroxide with acetic acid. Start by adding magnesium oxide or hydroxide to acetic acid in a controlled manner while stirring until the reaction is complete. Filter the solution to remove any insoluble impurities, and then evaporate the solvent to obtain solid magnesium acetate.
What acid do you add to magnesium to get magnesium chloride?
Hydrochloric Acid
