Red cabbage undicator

 Aim: I want to find out how red cabbage can tell if a liquid is an acid or a base.

Research: 1x YouTube video about Red Cabbage Indicators.

           


Method:

Equipment: 
  • Acid was hydrochloride Acid
  • Base was Sodium hydroxide 
  • Water
  • Cup/beaker
  • Test tube 
  • Dropper 
  • Red cabbage

Instructions: 
  1. Wash your hands
  2. Grab your equipment
  3. Put water into the beaker
  4. Cut the cabbage in little pieces and put it in the beaker with the water in it & mix the water with cabbage until its dark
  5. Grab the water colour of the cabbage beaker with the dropper and put some in each Test tube and you should count how many drops you put
  6. Get the Sodium Acid and Base acid 
  7. Put one of the acids or both in the test tubes and you should count how many drops you put in
  8. And make colours with the acids and cabbage water!
  9. Quest: Try to put more than 1 colour in a test tube without them mixing
  10. Now make your adventure of colours 😃

Results:     The colours went to dark to slowly light, the most surprising colour was yellow and when you could put another layer on a colour.           


Discussion:        Q1: What is an Acid and a Base-------------------

      HARDER EXPLANATION: An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. 

EASIER EXPLANATION: An acid is a substance that can donate a hydrogen ion (H+) to another substance. ... A strong acid will be able to let go of many or all of their hydrogen ions while a weak acid will hold onto some of their ions. Because acids donate hydrogen ions, all acids must have hydrogen in them.
  
                           Q2 :   What do chemical indicators do----------
 Chemical indicators are used to monitor whether the parameters to achieve sterilization have been met for a specific sterilization process.

                           Q3 : An ion is a special type of atom or molecule that has an electric charge. A hydrogen ion, then, is one that has a tiny electrical charge. Every substance in the universe is made up of hundreds and thousands of tiny atoms, molecules and ions. When a large number of those are hydrogen ions, the substance is acidic
