SUMMARY

This discussion clarifies the definitions of v/v (volume/volume), w/w (weight/weight), and normality in relation to molarity and solutions. Specifically, a 5% v/v sulfuric acid solution consists of 5% sulfuric acid by volume and 95% water, while a 10% w/w solution contains 10% sulfuric acid by weight and 90% water. Additionally, normality is discussed in the context of solutions, with an example of Silver Nitrate at 0.025 Normal. The provided link offers further detailed explanations on these concepts.

PREREQUISITES
  • Understanding of solution concentration terms: v/v, w/w, and normality
  • Basic knowledge of sulfuric acid and its applications
  • Familiarity with aqueous solutions and their properties
  • Concept of molarity and its relevance in chemistry
NEXT STEPS
  • Research the differences between molarity, molality, and normality in detail
  • Learn how to calculate concentrations for various chemical solutions
  • Explore the implications of using v/v and w/w in laboratory settings
  • Investigate the practical applications of sulfuric acid in chemical processes
USEFUL FOR

Chemistry students, laboratory technicians, and professionals involved in chemical purchasing and solution preparation will benefit from this discussion.

Examples: Sulfuric Acid 93%, Sulfuric Acid 5% v/v Aqueous Solution, Sulfuric Acid 10% w/w Aqueous Solution, Silver Nitrate 0.025 Normal.

How do I relate this to molarity and what does v/v, w/w, and normal mean?

Any help? I just need to know so that I can choose when purchasing chemicals.
 
v/v means volume to volume, so it would be 5% by volume sulfuric acid, and 95% by volume water (aqueous).

w/w means weight to weight, so 10% by weight sulfuric acid and 90% by weight water.

Here's a site that actually offers explanations to all your questions, and it does a better job than I could explaining normality.

Thanks a lot Moonbear!
