Answer

Explanation:

Step1: Calculate the pH value

The formula for pH is (pH = -\log[H^{+}]). Given ([H^{+}]=1.45\times 10^{- 10}) M. Then (pH=-\log(1.45\times 10^{-10})). Using the logarithm property (\log(ab)=\log a+\log b), we have (pH = -(\log1.45+\log(10^{-10}))). Since (\log(10^{-10})=- 10) and (\log1.45\approx0.161), then (pH=- (0.161-10)=9.839).

Step2: Determine the solution property

The pH scale: (pH < 7) is acidic, (pH = 7) is neutral, (pH>7) is basic. Since (pH = 9.839>7), the solution is basic.

Answer:

B. 9.839 basic
