the seaweed is soaked in alkali solutions such as potassium hydroxide. The heating is to separate the carrageenan from seaweed. Cellulose will then be mechanically removed by centrifugation and filtration. The remaining solution is evaporated to shed off any remaining water. The powdered carrageenan is...
Potassium hydroxide exists as a white solid powder, but is highly soluble in alcohols like ethanol. Ethanolic potassium hydroxide is highly acidic in nature. It is highly corrosive when handled. It is an effective conductor of heat, and highly flammable. It appears as a colorless liquid. Manufac...
The pOH scale is similar to the pH scale in that a pOH of 7 is indicative ofa neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution wi...
Classify each of these soluble solutes as either a strong electrolyte, a weak electrolyte, or a non-electrolyte a) Sulfuric acid- H2SO4 b) Potassium hydroxide- KOH c) Carbonic acid- H2CO3 d) Ammonia- NH3 e) Potassium chloride- KCl f) Butanol...
A0.150M solution of potassium hydroxide is used to titrate citric acid(citric acid has three acidic hydrogens per molecule).How many mLof potassium hydroxide will be needed to neutralize2.55gof citric acid?(Citric acid has a mo...
It contains iron, potassium and hydroxide. The interesting thing is that on Earth at least it needs highly acidic water to form. So we’ve got water or had it at one point. And since most planetary scientists believe that water is essential to life, the presence of jarosite means that on...
Potassium Citrate Diet Coke's sixth ingredient is citric acid, while Coke Zero's is potassium citrate. Citric acid is the acidic component of citrus fruits like lemons and limes. If you've ever made homemade jam or other canned foods, you may have purchased citric acid at the grocery ...
Well, in 2004, an exploration robot discovered jarosite there.Jarosite is a yellowish brown mineral with a crystalline structure that's also found on Earth.It contains iron, potassium and hydroxide.The interesting thing is that on Earth at least it needs highly acidic water to form.So we've ...
Why is potassium permanganate used in the process of distillation of water? Why boiling stones necessary to the distillation flask? How is nitric acid prepared industrially? Why is olive oil acidic? why Sudan IV dye is used for detecting the lipids ???
To visualize changes in the GBM acidic milieu we generated a Glycosylphosphatidylinositol (GPI) anchored pHluorin2 (Fig. 2A). The GPI anchor is a posttranslational modification to a protein that attaches it to the outer leaflet of the cell membrane, and pHluorin2 is a fluorescent protein ...
