Finding out the concentration of an acid or base

Click For Summary

Discussion Overview

The discussion revolves around methods for determining the concentration of acids and bases, specifically through thermochemistry and density measurements, rather than traditional titration methods. Participants explore experimental designs and applications related to these measurements.

Discussion Character

  • Exploratory, Technical explanation, Experimental/applied

Main Points Raised

  • One participant suggests using freezing point depression as a method to determine concentration.
  • Another participant mentions measuring specific gravity as a way to relate density to concentration, noting that relevant data is available in literature.
  • A different approach proposed involves adding water to the acid and measuring the heat released during the reaction to estimate concentration.
  • One participant inquires about the pharmaceutical applications of acid-base titration, indicating a broader interest in the topic.

Areas of Agreement / Disagreement

Participants present multiple methods for determining concentration, indicating a lack of consensus on a single approach. Various techniques are discussed without agreement on their relative effectiveness or applicability.

Contextual Notes

Some methods mentioned depend on specific conditions or assumptions, such as the availability of concentration vs. specific gravity data in literature. The discussion does not resolve the effectiveness of the proposed methods.

Hello I really need help for working out the concentration of an acid / base.

1) How can we use a simple thermochemistry measurement and a density measurement, to find the concentration of an acid or alkali? (other than titration)

2) How do you devise an experiment to estimate the concentration of an acid / alkali?
 
Chemistry news on Phys.org
1) freezing point depression; 2) look at the question again --- most people include the answer in the question statement.
 
I have 1 question?

What is the pharmaceutical application of acid-base titration?

Can anyone help me please?
 
Freezing point depression/boiling point elevation is one way to do it. As far as density measurements go, simply measure the specific gravity. Concentration vs. specific gravity data is widely available in literature.

Another more creative way to measure concentration is by adding water to the acid and measuring the heat that is released.
