Difference between Acids and Alkalis.

Acids:

1. Acid’s pH when measured by a pH scale is always below 7, the lower the pH the more acidic the substance is.

2. Acid turn the blue litmus paper to the color red.

3. Acids are sour.

4. Acids are rough and corrosive.

5. Acids can cancel the effect of an alkali to neutralize a solution.

6. Acids changes the color of a green universal indicator to the color red.

Examples of Acids:

• Hydrochloric Acid: "Used in laboratory purposes"

• Sulfuric Acid: "Used in car batteries"

• Citric Acid: "In Lemons"

Alkalis:

1. Alkali’s pH when measured by a pH scale is always above 7, the higher the pH the more alkaline a substance is.

1. Alkali turn the red litmus paper to the color blue.

2. Alkalis are bitter.

3. Alkalis are slippery and corrosive.

4. Alkalis can cancel the effect of an acid to neutralize a solution.

5. Alkalis change the color of a green universal indicator to the color purple.

Examples of Alkalis:

• Potassium Hydroxide: "Used in agriculture"

• Sodium Hydroxide: "Used in dyes"

• Calcium Hydroxide: "Used in food processing"
