Answer:
D
Step-by-step explanation:
Frizzy cola is 4.1 through 4.3 inclusive
This means that the pH Range of frizzy cola is between 4.1 to 4.3(including 4.3)
If the pH value is represented as h :
The the lower bound will be 4. 1
Upper bound will be 4.3
This means :
4.1 less than or equal to h and h is less than or equal to 4.3
4.1 ≤ h ≤ 4.3
Since, 7 is neutral, values below 7 are acidic while above 7 are alkaline ;
The range is below 7, hence, frizzy cola is acidic.
4.1 ≤ h ≤ 4.3 ; acidic
