pH Colours

 Aim: 

I want to find out what the colours of pH are.

Research:

Method

Equipment 

• Acid-Hydrochloric 
• Base-Sodium Hydroxide 
• Test tubes rack with test tubes 
• universal indicator 

instructions:

1. Get your Equipment 
2. but 10 drops of universal indicator 
3. Add different amounts of acid and base into the test tubes 
4. watch what happens to the colours

discussion:

When two or more substance combine, they create one or more new substance, which sometimes have different molecular structures from the original substance, meaning they absorb and radiate light in different ways, leading to a colour change.

how do you measure acid levels?

Red litmus turns blue in basic solutions, blue litmus turns red acidic solution, and neutral litmus (usually purple) turns red acidic solutions and blue in basic solutions. To find the specific pH of a sample, you will need pH test paper or strip that is more precise than a litmus strip.

what is an acid?

A substance with particular chemical properties including turning litmus red, neutralizing alkalis, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind
