How many H+ ions are there in a solution with a ph of 6 compared to a solution with a ph of 8?
A) 2000 less
B) 2000 more
C) 100 less
D) 100 more
Ph
A scale used to specify the acidity or basicity of an aqueous solution, with values ranging from 0 (highly acidic) to 14 (highly basic), and 7 being neutral.
H+ Ions
Positively charged hydrogen atoms, also known as protons, which play a crucial role in acid-base chemistry and cellular energy production.
- Understand the pH scale and the concentration of H+ ions in solutions.

Final Answer :
B
Explanation :
The pH scale is logarithmic, meaning each whole pH value below 7 is 10 times more acidic than the next higher value. Therefore, a solution with a pH of 6 has 10^2 = 100 times more H+ ions than a solution with a pH of 8. None of the provided options accurately describe this relationship, but option B is the only one that suggests there are more H+ ions at pH 6, which is correct in a comparative sense, despite the numerical inaccuracy.
