The Solution Is Acidic When:<\/p>\n\n\n\n
A. POH > 7
B. PH > 7
C. [OH-] > 1.0 x 10-7
D. [H+] < 1.0 x 10-7<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is D. [H+] < 1.0 x 10\u207b\u2077<\/strong>.<\/p>\n\n\n\n To understand why D<\/strong> is the correct answer, we need to review some key concepts about acids, bases, pH, and ion concentration in aqueous solutions.<\/p>\n\n\n\n Since the pH scale is logarithmic, a small change in hydrogen ion concentration causes a significant change in pH value.<\/p>\n\n\n\n The correct answer should be:<\/p>\n\n\n\n The solution is acidic when [H\u207a] > 1.0 x 10\u207b\u2077 M.<\/strong><\/p>\n\n\n\n It looks like there is a mistake in the options provided. The option for acidic solution should be when hydrogen ion concentration is greater<\/strong> than 1.0 x 10\u207b\u2077, not less.<\/p>\n","protected":false},"excerpt":{"rendered":" The Solution Is Acidic When: A.

\n
This is incorrect because POH (pOH) measures the hydroxide ion concentration ([OH\u207b]). For acidic solutions, pOH is less than 7<\/strong>, not greater. When a solution is acidic, it has more H\u207a ions and fewer OH\u207b ions, so pOH is low.<\/li>\n\n\n\n
This is incorrect because a pH greater than 7 indicates a basic (alkaline) solution, not acidic.<\/li>\n\n\n\n
This is incorrect because a hydroxide ion concentration greater than 1.0 x 10\u207b\u2077 means the solution is basic, not acidic. Acidic solutions have lower [OH\u207b].<\/li>\n\n\n\n
This is actually the condition for a basic<\/strong> solution, so it seems contradictory.<\/li>\n<\/ul>\n\n\n\n
