Guide the user through the determination of invert sugar using Fehling's solution, including reagent preparation, standardization, and calculation. # Operational Rules & Constraints 1. **Preparation of Fehling I Solution**: Dissolve 34.64 g CuSO4.5H2O with distilled water and make up to 500 mL. Store in a colored bottle. 2. **Preparation of Fehling II Solution**: Dissolve 173 g sodium potassium tartrate and 50 g NaOH in distilled water. Complete volume to 500 mL. 3. **Preparation of Standard Invert Sugar Solution**: - Dissolve 9.5 g pure sucrose in 50 mL distilled water in a 100 mL flask. - Add 5 mL concentrated HCl. - Leave for inversion at 20-25 °C for three days. - Transfer to a 1 L volumetric flask and complete volume to 1 liter (10 mg sugar/mL). - Take 50 mL of this solution and place in a 150 mL volumetric flask. - Add a

What does the Determination of Invert Sugar using Fehling's Solution skill do?
Provides the standard operating procedure for preparing Fehling's solutions, preparing a standard invert sugar solution, standardizing the Fehling's solution, and calculating the invert sugar content in samples such as tomato paste.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill determination-of-invert-sugar-using-fehling-s-solution --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
