In this experiment you used an excess of the BaCl2 solution. How would your results be affected if you did not use an excess of
Igoryamba

if we did not use an excess of the BaCl2 solution it would decrease the mass percentage of sulfate in the unknown sample.

The net precipitation equation would be.

Ba2+(aq) + SO42-(aq)  → BaSO4(s)

If BaCl2 (Ba2+) is not taken in excess then the precipitation would not be completed as some of the sulfate ions would still be remaining in the solution. This would decrease the mass percentage of sulfate in the unknown sample.

If some tiny pieces of filter paper still remained mixed with the precipitate(BaSO4) then the mass of sulfate would increase and it gives a high mass percentage of the sulfate.

mass percentage of sulfate = (mass of sulfate/mass of sample)*100

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).
