Answer 2

Answer:

• The acid turns the blue litmus to red. The acid rich fluid includes hydrochloric acid, nitrous acid, and sulphuric acid.  
• The red litmus paper turns blue in alkaline condition. The basic acidic profile is 4.5 to 8.3 at room temperature of around 25 degree Celsius which is equal to 77 degree Fahrenheit.
• The neutral paper is purple. The ammonia turns red litmus paper in to blue being strongly alkaline in nature.
