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 first rule when substituting one vinegar for another: Color is not the best indicator. While rice vinegar and white vinegar may be closer in color, rice vinegar is incredibly sweet and delicate, while white vinegar is sour and harsh. White wine and white balsamic vinegars are rich, fruity, and tangyâstill a bit stronger than rice vinegar. The best substitute is cider vinegar: Itâs mild, with a faint apple flavor that wonât overpower (though when used for pickling, the apple flavor will be much more pronounced).
