Integers Rules ADDITION When we ADD a POSITIVE number we move UP the number line. e.g. (-3) + 7 = 4 When we ADD a NEGATIVE number we move DOWN the number line. e.g. 2 + (-8) = -6 SUBTRACTION When we SUBTRACT a POSITIVE number we move DOWN the number line.ntegers Rules ADDITION When we ADD a POSITIVE number we move UP the number line. e.g. (-3) + 7 = 4 When we ADD a NEGATIVE number we move DOWN the number line. e.g. 2 + (-8) = -6 SUBTRACTION When we SUBTRACT a POSITIVE number we move DOWN the number line.
Commercially sold distilled white vinegar in the US is acetic acid in water, at a concentration of 5% by mass for a pH of around 2.4â2.6. If you add water to it, the pH will go up. If you distill it (vinegar is more volatile than water) the resulting distillate will have a lower pH.
The most neutral flavored vinegar is white vinegar, but we wouldn't likely use this in a vinaigrette. At the very least, use a white wine vinegar. But the flavors and types of specialty vinegar, like balsamic, sherry or raspberry, are as varied and diverse as can be.
