A solution at ph 10 contains __________ than the same amount of solution at ph 8.
Sindrei [870]

100 times less H+

A solution at ph 10 contains<u> </u><u>100 times less H+</u> than the same amount of solution at ph 8.

<h3>The pH scale: How does it function?</h3>
  • The pH scale determines how acidic or basic water is.
  • The range is 0 to 14, with 7 representing neutrality.
  • Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

<h3>How does the pH change when two acids are combined?</h3>
  • An acid's strength increases with the quantity of hydrogen ions it releases.
  • The pH of the strong acids is between 1 and 2.
  • We may observe that there is no response when two acids of the same strength are combined.
  • It's because the end product will be neutral and the pH won't change.

<h3>How is pH value determined?</h3>

There are two ways to measure pH:

  • colorimetrically with indicator fluids or sheets
  • electrochemically with electrodes and a millivoltmeter for greater accuracy (pH meter).
