Pick a solution in your home, work, or even outside (be sure to check the label to make sure that whatever you are measuring is nonhazardous and water based)

Answer:

Acids are substances that taste sour while bases are slippery when touched.

Step-by-step explanation

The following are the properties of acids:

• Acids turn the color of blue litmus paper to red.
• All acids taste sour or tart.
• Their pH range is from 0 to 6.
• Acids lose their acidity when combines with bases.
• They change the color of Methyl to Orange/Yellow to Pink.
• Acidic substances convert Phenolphthalein from deep pink to colorless.
• Acids reduce the basicity of bases.
• Most acids are corrosive, they tend to corrode or rust metals.
• They produce positive hydrogen ions (H+) when mixed with water.
• Acids react with metals and form hydrogen gas.
• Acids produce carbon dioxide when reacted with carbonates.

The following are the properties of bases :

• Bases are slippery to touch when in aqueous form.
• Generally, bases have a bitter taste.
• Bases produce hydroxyl ions (OH-) when mixed with water.
• The pH range of bases is from 8 - 14.
• Bases turn the color of red litmus paper to blue.
•  Bases lose their basicity when mixed with water

Experiment: 

1. Chop some red cabbage and put it in a mixer or a blender.
2. Add water to it and mix it until a juice is prepared.
3. Strain this mixture into a glass.
4. Take different substances like lemon, milk, vinegar, ammonia, bleach etc and mix it with the red cabbage solution.
5. The color of the substance will change according to their acidity of basicity.

Observation: Acidic substances change the color of the solution from purple to red or pink. Neutral substances turn the purple solution to blue. Basic substances change the color of the purple solution to green or yellow.
