Answer
a. Basic
b. Basic
c. Acidic
d. Basic
Work Step by Step
Acidic solutions have a pH lower than 7, while basic solutions have a pH higher than 7, and neutral solutions have a pH of 7.
a. basic because pH is higher than 7 and thus [H+] is lower.
b. basic because pH is higher than 7 and thus [H+] is lower.
c. acidic because pH is lower than 7 and thus [H+] is higher.
d. basic because pH is higher than 7 and thus [H+] is lower.
