What is the best way to determine whether a substance is an acid or base?

A pH meter gives a direct reading which is great when testing wine or soft drinks. Litmus paper will go red in acid or blue in base. An acid will liberate carbon dioxide from chalk - a base will not You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic.

How could you tell if a food may contain an acid or a base?

You can tell when you drink or eat lemons, lemonade, grapefruit, apples, oranges, bananas and etc . it will taste sour or bitter. Sour means acid. Bases tend to be bitter - but tasting strong bases is very dangerous. Hopefully you will never try testing something like drain cleaner to find out.


What does an universal indicator tell you about an acid that litmus doesn't?

Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.


How can you tell an acid from a base?

You can tell by testing it with either universal indicator solution or with litmus paper.There are other methods, but some of them are not exactly safe: acids usually taste sour (do not try this) and bases usually taste bitter (do not try this either). Also, bases tend to feel "slippery" (at the risk of sounding like a broken record, do not try this).

Is washing powder an acid or a base?

Yes, it is. You can tell weather something is an Alkali, Neutral pr acid via the pH scale or, you can tell if something is an alkali from its consistency; if it is sludgy (like washing-up liquid), it is an alkali. So, I am under the influence that washing-up POWDER is too, an alkali.J.S.P. Aged 11


How can you tell if a food contains an acid or a base?

If its acidity level is below 7, then it is a acid. If it is above a seven, then it is a base. If it is exactly 7 then it is neutral such as water.


Is the formula HCI a base?

If you meant HCl, Hydrochloric Acid, it is a strong acid and not a base. A way to tell if it is an acid is that it has an H+ in the chemical formula. Most of the time, if it is a base it has an OH- attached to the chemical formula, but this is not necessarily true for all bases.
