Explanation:
the element is named after the latin word for calcium 'calx'
Chloroplasts help them detect light. Chloroplasts are also contained in plants.
The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ =
(for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ =
(for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
