Answer
Explanation:
Step1: Recall pH - based classification
Acids have pH < 7, bases have pH > 7, and neutral compounds have pH = 7. Litmus paper turns red in acids, blue in bases and purple in neutral substances.
Step2: Classify pH - 7
Neutral, since pH = 7 represents a neutral compound.
Step3: Classify "Turns litmus paper red"
Acid, as acids turn litmus paper red.
Step4: Classify calcium hydroxide
Base, as metal hydroxides are bases.
Step5: Classify H₂S
Acid, hydrogen - containing non - metal compounds are often acids.
Step6: Classify pH 13
Base, since pH > 7.
Step7: Classify water
Neutral, pure water has pH = 7.
Step8: Classify "Turns litmus paper purple"
Neutral, as neutral substances turn litmus paper purple.
Step9: Classify Sr(OH)₂
Base, metal hydroxides are bases.
Step10: Classify pH 2
Acid, since pH < 7.
Step11: Classify coffee
Acid, coffee is acidic in nature.
Step12: Classify hydrobromic acid
Acid, it is an acid as the name suggests.
Step13: Classify bleach
Base, bleach is usually basic.
Answer:
pH 7: Neutral Turns litmus paper red: Acid Calcium hydroxide: Base H₂S: Acid pH 13: Base Water: Neutral Turns litmus paper purple: Neutral Sr(OH)₂: Base pH 2: Acid Coffee: Acid Hydrobromic acid: Acid Bleach: Base
