Solving Titration Problems

Solving Titration Problems-39
For a strong acid paired with a strong base, the p H at equivalence is 7.For a strong acid titrant and weak base analyte, take the number of moles of weak base originally present and divide by the new total volume (original volume of analyte volume of titrant added to reach equivalence) to find concentration, then take the negative log of this concentration.For a list of common acids and bases, see the link in the Resources section.

Use the data you've been given to calculate p H at each step of the reaction if the problem asks you to do so (if not, skip this step and proceed to Step 6).

Depending on the identities of analyte and titrant, there are four possibilities.

Then convert from p OH to p H by subtracting from 14.

Find the p H at equivalence if the problem asks you to do so.

This trivia quiz is based on the titration problem of acids and bases that we learned and had some practice in the lab this week.

Solving Titration Problems Affordable Essay Writing

When chemists need to find the concentration of a substance dissolved in a solution, they often use a technique called titration.

Therefore, at that point in the titration you are dealing with a HCO Math Science Biology Physics Biochemistry Organic Chemistry Moles Stoichiometry Chem Ap Chemistry ...

Titration is a process of slowly adding one solution of a known concentration to a known volume of an unknown concentration until the reaction gets neutralized.

2) If the analyte is a strong base and the titrant is a strong acid, the steps you follow are the same as in (1) except that the negative log of the analyte concentration will give you the p OH instead of p H. 3) If the analyte is a weak acid and the titrant is a strong base, use the Henderson-Hasselbalch equation, p H = p Ka log ( [conjugate base concentration] / remaining weak acid concentration ).

The amount of conjugate base is equal to the amount of titrant you've added so far; divide it by total volume to find concentration.
