Strong Acid-Strong Base Titration:
| From: | To: |
Strong acid-strong base titration is a laboratory technique used to determine the concentration of an acid or base by neutralizing it with a base or acid of known concentration. The equivalence point occurs when moles of acid equal moles of base.
The calculator uses the titration formula:
Where:
Explanation: The calculation differs based on the titration stage (before, at, or after equivalence point).
Details: Accurate pH calculation helps determine the equivalence point, select appropriate indicators, and understand the titration curve behavior.
Tips: Enter concentrations in mol/L, volumes in mL. All values must be positive numbers. The calculator will determine the titration stage and calculate pH accordingly.
Q1: Why is pH 7 at equivalence point for strong acid-strong base titration?
A: Because the salt formed from strong acid and strong base hydrolysis doesn't affect pH, resulting in a neutral solution.
Q2: What is the shape of a strong acid-strong base titration curve?
A: It shows a steep vertical region around the equivalence point with pH changing rapidly with small additions of titrant.
Q3: How do I choose an indicator for this titration?
A: Choose an indicator whose color change range (pH transition interval) falls within the steep portion of the titration curve (typically pH 4-10).
Q4: What factors affect titration accuracy?
A: Concentration accuracy, measurement precision, indicator selection, and proper technique all affect titration results.
Q5: Can this calculator be used for weak acid/weak base titrations?
A: No, this calculator is specifically designed for strong acid-strong base titrations which have different calculation methods.
