Which PH Indicates A Basic Solution? 1. 1 2. 5 3. 7. 4. 12<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/strong><\/p>\n\n\n\n

The correct answer is: 4. 12<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The pH scale<\/strong> is a measurement of how acidic or basic (alkaline) a solution is. It ranges from 0 to 14<\/strong> and is a logarithmic scale, meaning each whole number change represents a tenfold difference in hydrogen ion concentration.<\/p>\n\n\n\n

    \n
  • Acidic solutions<\/strong> have a pH less than 7<\/strong>.<\/li>\n\n\n\n
  • A neutral solution<\/strong> has a pH equal to 7<\/strong> (pure water is a common example).<\/li>\n\n\n\n
  • Basic (alkaline) solutions<\/strong> have a pH greater than 7<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Let\u2019s briefly evaluate each option:<\/p>\n\n\n\n

      \n
    1. pH 1<\/strong> \u2013 This is highly acidic. It corresponds to substances like stomach acid or battery acid.<\/li>\n\n\n\n
    2. pH 5<\/strong> \u2013 This is mildly acidic, similar to black coffee or rainwater.<\/li>\n\n\n\n
    3. pH 7<\/strong> \u2013 This is neutral, like distilled water.<\/li>\n\n\n\n
    4. pH 12<\/strong> \u2013 This is strongly basic<\/strong>. It\u2019s the correct answer. Common examples of solutions with a pH of 12 include soapy water and bleach.<\/li>\n<\/ol>\n\n\n\n

      Why is pH 12 Basic?<\/h3>\n\n\n\n

      A basic solution<\/strong> has more hydroxide ions (OH\u207b)<\/strong> than hydrogen ions (H\u207a)<\/strong>. When the concentration of hydrogen ions decreases, the pH increases above 7. A pH of 12 indicates a very low concentration of H\u207a ions and a high concentration of OH\u207b ions, typical of substances like household ammonia or cleaning agents.<\/p>\n\n\n\n

      The pH scale is crucial in chemistry, biology, environmental science, and medicine. For instance, our blood must maintain a slightly basic pH of about 7.35\u20137.45. Deviations from this range can be dangerous.<\/p>\n\n\n\n

      In conclusion, among the given options, pH 12 is the only value that indicates a basic solution<\/strong>, making it the correct choice.<\/p>\n\n\n\n
