Acids & Bases

A:

The pH level of lemon juice is about 2.0. Anything below 7 for pH levels means that it is an acid. Lemon juice is a strong acid. Lemons are strong in acidity because they are made of citrus juice and ascorbic acid.

  • How Does Soil Affect the PH of Water?

    Q: How Does Soil Affect the PH of Water?

    A: Depending on the chemicals in the soil, the pH of water passing through it increases, decreases or remain the same. In areas where water passes through soil containing limestone, dissolving the calcium carbonate in water creates a buffer solution, tying up the hydrogen or hydroxyl ions in the water so the pH becomes less likely to change.

  • 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.

  • How Are Acids and Bases Different?

    Q: How Are Acids and Bases Different?

    A: Acids and bases differ in chemical structure and reactions, pH level and taste. When interacting with phenolphthalein and litmus, each changes to a different color. Substances with a pH greater than seven are basic and those with a pH less than seven are acidic. Acidic substances taste sour, while basic substances are bitter.

  • 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 Importance of Acids and Bases?

    Q: What Is the Importance of Acids and Bases?

    A: Acids are used in industries to manufacture fertilizers, paints, dyes and man-made fibers, while bases are used in the production of fabrics, cleaning agents and paper. In nutrition, diluted acids are used to dress salads and vegetables, giving food a distinctive taste. For example, vinegar contains 3 percent acetic acid. Citrus fruits have citric acid. Aspirin contains acetylsalicylic acid, and wine has tartaric acid.
