Question
In your own words, define the following terms: conditioning endpoint indicator molar concentration (M) mass/mass percent concentration (m/m %) standardization titration 2. Observe and record the following buret readings. 31 3. When approaching the endpoint for the titration, how can you tell that you are very close? What volume of NaOH is required to flip the indicator from colorless to pink at the endpoint? 4. If KHP sample #1 requires 27.30 mL of NaOH solution to reach an endpoint, what volume should be required for samples #2 and #37 5 If vinegar sample #1 requires 30.15 mL of NaOH solution to reach an endpoint, what volume should be required for samples #2 and #37Explanation / Answer
1. Conditioning: it is a process in which reaction factors are stabilized or enhanced. Conditioning increases the probability of obtaining accurate results.
Endpoint: the endpoint refers to that point in which the indicator changes color in a colorimetric titration
Indicator: an indicator is a chemical substance that changes its physical appearance, that is color, when it reacts with a certain volume of a reactant.
Molar concentration: it is a measurement of concentration of a substance expressed in number of moles of solute/ volume of solution in litres.
Mass/mass% concentration: this is a measurement unit of concentration of a compound in a solution measured as mass of solute/ mass of solution *100
Standardization: it is a process of determining the exact concentration of a solution.
Titration: it is a technique where a solution of known concentration is used to determine the concentration of an unknown solution.
