SUMMARY

The discussion centers on the impact of dilution on pH levels when adding water to an acid solution. It is established that while adding water to an acid with a pH of 3 will raise the pH slightly due to dilution, it will not make the solution basic. The molarity of the acid and the specific type of acid used are critical factors in determining the extent of pH change, which can be measured using litmus paper or a pH meter.

PREREQUISITES
  • Understanding of pH scale and its implications
  • Knowledge of acid-base chemistry
  • Familiarity with molarity and its calculations
  • Experience with pH measurement tools, such as litmus paper and pH meters
NEXT STEPS
  • Research the effects of dilution on pH in different acid solutions
  • Learn about the properties of various acids and their dissociation constants
  • Explore the use of pH meters versus litmus paper for accurate pH measurement
  • Investigate the concept of molarity and its role in acid-base reactions
USEFUL FOR

Chemistry students, laboratory technicians, and anyone interested in understanding acid-base reactions and pH measurement techniques.

Hi all

I have been reading over difference sites when they discuss pH and water and acids.
I have under stood most of it.
If I change the pH of an acid of say 3, to basic, i add water and this raises the pH of the subatance

What I want to know is, does the molarity matter and type of acid I use matter or not if i want to see the change in pH myself by using litmis paper or a pH meter?

Nope. Try again. Adding water won't make it basic but it will raise pH slightly due to dilution.

Yes molarity matters as does the type of acid.
