Question


Compare pure water and coffee. Their pH differs by approximately

Answer 1

They differ by two positions in the pH scale.

Step-by-step explanation:

Hello,

In this case, since coffee has an pH of about 5 which is slightly acidic and water has a pH of 7, their pH differs by 2 approximately:

`\Delta pH=pH_(water)-pH_(coffee)=7-5=2`

Such acidity in the coffee is caused by the presence of the well-known chlorogenic acid which is besides helpful for us towards reducing the degree of tiredness we eventually acquire along the day.

Best regards.
