20 lip 2024 · Prepare sodium hydroxide solutions using this handy reference table which lists the amount of solute (solid NaOH) used to make 1 L of base solution. Follow these lab safety guidelines: Don't touch sodium hydroxide!
31 sie 2014 · The concentration of sodium hydroxide solutions can be determined by titrating a known amount of dried potassium hydrogen phthalate. If you really need an exact concentration of the solution, make it slightly more concentrated, standardize it and then dilute it to get the concentration desired.
Sodium hydroxide (lye) makes food too alkaline for bacterial growth. Lye will saponify fats in the food, which will change its flavor and texture. Lutefisk uses lye in its preparation, as do some olive recipes.
The sodium content of selected fruits, vegetables, beans, and legumes is shown in Table 4-10. Pickled vegetables such as sauerkraut and cucumbers are also high in sodium because of the salt added to drive the fermentation process and to maintain a crisp texture (Brady, 2002).
There are two ways to express food acidity: Titratable acidity. Hydrogen concentration (pH) Simple estimate of the total acid content of food. Also called total acidity. Better predictor of acid impact on flavor. Depend on the strength of acid condition. Also called active acidity. Quantify only the free H3O+ concentration.
In this experiment, you will make soap from a fat or an oil by heating it with sodium hydroxide. You will precipitate the soap by adding it to a concentrated salt solution, and then you will collect the solid soap using vacuum filtration.
