Edexcel IAL Chemistry AS 8.23 Core Practical 4 standard solution
Edexcel IAL Chemistry AS 8.23 Core Practical 4 standard solution
Calculate the required mass, dissolve and transfer every portion into a volumetric flask, make to the mark and invert before using a mean titre and mole ratio.
How this is tested
- Calculate solid mass from target volume, concentration and hydrated molar mass.
- Describe quantitative transfer, making to the mark and mixing a volumetric flask.
- Use the mean titre and balanced equation to calculate the unknown NaOH concentration.
