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.
No, it's not. White vinegar (also known as distilled vinegar) is made of acetic acid diluted in distilled water. Its flavor is simpleâits just sour.
