Question

identify the ph of each substance. then, classify them as acidic, neutral or basic.
ammonia \tph= \t☐ acidic
\t\t\t\t\t\t☐ neutral
\t\t\t\t\t\t☐ basic
baking soda \tph= \t☐ acidic
\t\t\t\t\t\t☐ neutral
\t\t\t\t\t\t☐ basic
bleach \tph= \t☐ acidic
\t\t\t\t\t☐ neutral
\t\t\t\t\t☐ basic
coffee \tph= \t☐ acidic
\t\t\t\t\t☐ neutral
\t\t\t\t\t☐ basic
cola \tph= \t☐ acidic
\t\t\t\t\t☐ neutral
\t\t\t\t\t☐ basic
drain cleaner \tph= \t☐ acidic
\t\t\t\t\t\t☐ neutral
\t\t\t\t\t\t☐ basic
hand soap \tph= \t☐ acidic

Explanation:

Step1: Assign known pH values

• Ammonia: $\text{pH}=11$
• Baking Soda: $\text{pH}=9$
• Bleach: $\text{pH}=13$
• Coffee: $\text{pH}=5$
• Cola: $\text{pH}=3$
• Drain Cleaner: $\text{pH}=14$
• Hand Soap: $\text{pH}=10$

Step2: Classify by pH range

Substances with $\text{pH}<7$ = Acidic; $\text{pH}=7$ = Neutral; $\text{pH}>7$ = Basic

• Ammonia ($11>7$): Basic
• Baking Soda ($9>7$): Basic
• Bleach ($13>7$): Basic
• Coffee ($5<7$): Acidic
• Cola ($3<7$): Acidic
• Drain Cleaner ($14>7$): Basic
• Hand Soap ($10>7$): Basic

Answer:

Substance	pH	Classification
Baking Soda	9	Basic
Bleach	13	Basic
Coffee	5	Acidic
Cola	3	Acidic
Drain Cleaner	14	Basic
Hand Soap	10	Basic
