  • Is HCN a strong acid?

    Q: Is HCN a strong acid?

    A: Hydrogen cyanide, or HCN, is not a strong acid. In solution, hydrogen cyanide is a weak acid that is mostly HCN with minimal amounts of hydronium and cyanide ionized. A weak acid partially ionizes in solution. The solution moves backwards and forwards to create the products and reactants.

  • What does stomach acid do?

    Q: What does stomach acid do?

    A: Stomach acid breaks down food so that it is more easily absorbed by the body, according to MedicineNet. Muscles in the wall of the stomach churn the food, stomach acid and enzymes together to create a thick liquid, known as chyme, that moves into the small intestine for further digestion.

  • What is the pH level of hydrochloric acid?

    Q: What is the pH level of hydrochloric acid?

    A: The pH of hydrochloric acid is 0. This reading is taken from a solution of 1 mole of hydrochloric acid. A less concentrated solution of the acid, such as a 0.5-mole solution, has a higher pH, meaning it would be less acidic.

  • What is the difference between an acid versus a base?

    Q: What is the difference between an acid versus a base?

    A: An acid is a substance that donates a proton, and a base is a substance that accepts a proton. A base is a chemical compound that forms OH- ions when dissolved in water and reacts with acids to form salts. An acid is a chemical compound that forms H+ ions when dissolved in water and reacts with bases to form salts.
