  1. Acids and bases By: Noor 7C

  2. What is an Acid An acid is an chemical substance. Acids are things that have a ph scale less than 7. Acids can dissolves some metals, neutralizes alkalis, and turns litmus red. Acids can also burn your skin and contain hydrogen which dissolves in water.

  3. Here are some examples of Acids • Carbonic Acid (Soft drink) Ascorbic Acid ( Vitamin C) (fruits) Tannic Acid (Tea)

  4. What is base? A base is a chemical substance that donates electrons or hydroxide ions or that accepts protons. Base has a ph scale more than 7. It can burn your skin and turn litmus paper blue. Base has many alkies and reacts with acid from salt and water.  

  5. Here are some some examples of Bases Calcium hydroxide (lime water) Sodium hydroxide (caustic sodium) Magnesium hydroxide (Milk)

  6. What is the universal indicator? A universal indicator is chemical solution made from a mixture of substances which produce many different color Changes corresponding to different pH levels, used to discover how acid or alkaline something is.

  7. What is the PH scale? The pH scale measures how acidic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is an acid. A pH greater than 7 is a base.

  8. This is how a ph scale looks like

  9. What is tooth decay? Tooth decay is the process of teeth destruction by acids. Decay occurs when plague combines with sugars or starches of food that we eat, and when they go into your teeth your tooth becomes more of an acid and become weaker.To prevent tooth decay brush twice a day, because toothpaste contains fluoride acid that helps kill the bacteria on the teeth.
