Notes. 1  For a quick gluten-free gravy, while the roast is cooking, heat 2 Tbsp of butter/fat in a sauce pan. 2  If you are making the roast ahead of time, it is a great idea to use the broth left in the roasting pan to make this gravy as directed above. 3  Stretch this meal by braising extra root veggies on the side.
The remaining part of the original water molecule is called a hydroxide ion (negative charge because it kept an extra electron, shorthand = OH-). Although present at very low levels in solution, H+ and OH- ions can have enormous effects on the properties of a solution, especially when they are not in balance. In pure water, every hydroxide ion that forms creates a hydrogen ion, so there are equal numbers of anions and cations.
In a strong acid, nearly all the acid molecules form ions. In a weak acid, only some of the acid molecules form ions. The more OH- ions (hydroxide ions), the more alkaline an alkali will be. In other words, the more OH- ions there are the higher the pH number.
