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.
1 An Arrhenius acid is a compound that increases the H ion concentration in aqueous solution. 2  An Arrhenius base is a compound that increases the OH ion concentration in aqueous solution. 3  The reaction between an Arrhenius acid and an Arrhenius base is called neutralization and results in the formation of water and a salt. It is neither an acid nor a base. ( 2 In fact, it is the formula for methanol, an organic compound.). 3  This formula also has an OH in it, but this time we recognize that the magnesium is present as Mg cations. 4  As such, this is an ionic compound of the OH ion and is an Arrhenius base.
