There is no such thing as a purple star.
When something is electrically neutral it has neither a positive nor a negative charge.
true
UTC is french - Temps Universel Coordonné. In translates to Universal Coordinated Time. It is essentially the same as Greenwich Mean Time. The military calls it Zulu.
if acid not very acidic if base not very basic more like neutral
If you mean a universal indicator, it is used to detect if a chemical is acid, alkali or neutral. It changes colour to show the chemicals position on the pH scale A universal indicator turns red at pH1 (Very acidic), orange at pH4 (Fairly acidic), yellow at pH6 (Not very acidic) and green at pH7 (Neutral). It turns more dark blue as it gets to pH10 (Quite Alkaline) and more to purple by ph12 (Even more alkaline) and to a dark purple by pH14( Very Alkaline).
There are a huge range of indicators that can be used in chemistry, but I presume you'll be using the basic 'universal indicator' here. A base will turn this indicator (depending on its strength) light/dark blue, or purple if it is quite strong. Or do you mean in terms of chemical reaction?
Red cabbage or beetroot juice will do the job.
I don't know what you mean by "universal indicator". That's a generic term for a mixture of indicators that displays distinct colors over a fairly broad pH range, but without knowing which specific one you're using it's difficult to say. However, a lot of them are minor variations on Yamada's 1923 patent, so I'd expect that it would probably be somewhere in the greenish part of the spectrum. Exactly where depends on the particular ratios of the various indicator compounds used.
They mean whether or not the pillow should be burnt by the aliens who invade the universal studios by the colour purple hat
they are too expensive to get hold of
Please see related link (table with some common pH values). I think this is what you mean. If you are referring to universal indicator strip look to the back of the card.
With PH indicators, showing acidity and alkalinity, green is neutral, blue-purple is alkaline, yellow-red is acid.
indicator lights means the vehicle is turning
what need to do when indicator light is on
universal theme
If you mean with a neutral then yes.
