Answer:

They differ by two positions in the pH scale.

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:

[tex]\Delta pH=pH_{water}-pH_{coffee}=7-5=2[/tex]

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.
