- by changing color
The PH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic
Blue ---- Green ---- Red = pH scale
Acid ------Neutral-----Base
-All acids contain hydrogen ions and they release them in water.
*Hydrochloric Acid - What is an acid?
- it is capable of corroding and dissolving a substance.
*Sodium Hydroxide - What is a base?
- A substance that, in aqueous, release hydroxide
*What is a Neutralization reaction?
- When an acid reacts to a base react to form water and salt and involves the combination.
Experiment:
Explanation: We mixed other bases of Acids and find out the colors
Green - Sudiom Hydroxide + Universal Indicator + Hydrochloric Acid + Universal Indicator
Red - Hydrochloric Acid + Universal Indicator + Sodium hydroxide
Orange - Hydrochloric Acid + Universal Indicator
Blue - Sodium Hydroxide + Universal Indicator
Light Blue Sodium Hydroxide + Universal Indicator + Sodium Hydroxide
Good Job Ace! You have included some great images :) There are few places where you have muddled the colours- remember RED= Acid, BLUE= Base. Why did the combinations of chemicals make different colours (how come the blue was blue, why did the red form?)
