Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 'II' is more basic than 'I'..
Key Points
- The pH scale ranges from 0 to 14, with 7 being neutral.
- A pH value below 7 indicates an acidic solution, while a pH value above 7 indicates a basic solution.
- Solution 'I' has a pH of 8, which means it is basic.
- Solution 'II' has a pH of 10, which means it is more basic than solution 'I'.
- Therefore, the correct statement is that 'II' is more basic than 'I'.
Additional Information
- Acidity and Basicity
- Acidity refers to the concentration of hydrogen ions (H+) in a solution.
- Basicity refers to the concentration of hydroxide ions (OH-) in a solution.
- Neutralization Reactions
- These are chemical reactions in which an acid and a base react to form water and a salt.
- Neutralization reactions typically result in a solution with a pH closer to 7.
- Indicators
- Indicators are substances that change color in response to changes in pH.
- Common indicators include litmus paper, phenolphthalein, and bromothymol blue.
