9 is not acidic at all, it's actually basic. 5 is acidic.
It cannot be basic since all alkalis/bases end or have OH (hydroxide) in the equation making this acidic
No. A number of metal oxides are basic.
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
You seem to be confused. acidic and basic are not things, they are properties. For example, vinegar is a solution, and it is acidic, because in solution, it dissolves to release hydrogen ions. Basic solutions, such as bleach, either accept hydronium ions in solution, or release hydroxide ions in solution. But all solutions, with the exception of distilled water, is either definatively acidic or basic. Look up a pH meter or a pH scale. The lower the number, the more acidic a solution is. The higher the number is, the more basic a solution is, and if it is 7.0, then it is neutral.
no it's not all purpose flour..
Self-rising flour has soda in it. All Purpose is basic flour, so you'd have to add soda to it. Cake Flour has been milled finer than the other two, so neither of these would make good cake flour.
yes enriched flour can be substituted for all purpose flour in a cake
all purpose flour has bleach in it, therefore when you eat anything made with all purpose flour you are eating bleach.
There is no difference between plain flour and all-purpose flour. They are one and the same. All-purpose (plain) flour does not contain the salt and baking soda that self-rising flour has.
yes. They are the same thing. Plain flour is an Australian term where all-purpose is the American.
How can I tell if flour is self-rising or all purpose? How can I tell if flour is self-rising or all purpose?
No. Some cake flours contain corn starch. Pastry flour, or all-purpose flour, does not.
All flour is unsifted until you sift it. Al purpose included.
all purpose flour
Yes. All-purpose flour and unbleached flour are usually the same thing. Just be sure that the package doesn't say something like 'self rising', 'bread flour', or 'cake flour' - those ARE NOT all-purpose flour.
It is bread flour.
