Answer
a. The solution is neutral.
b. The solution is acidic.
c. The solution is acidic.
d. The solution is acidic.
Work Step by Step
- If $pH \gt 7$, the solution is basic;
- If $pH \lt 7$, the solution is acidic;
- If $pH = 7$, the solution is basic.
a. Since $pH = 7.00 = 7$, the solution is neutral.
b. Since $pH = 2.38 \lt 7$, the solution is acidic.
c. Since $pH = 4.00 \lt 7$, the solution is acidic.
d. Since $pH = 5.93 \lt 7$, the solution is acidic.
