You can use indicators (liquid or paper). Universal Indicators (UI) are the best, as with them you can tell if something is acid, neutral or alkali, depending on the colour (there will be a colour indicator). However, you can also use red and blue indicator, but they are less accurate, as although they might be acid (or alkali), they might be neutral as well, so I suggest you use UI.
Hope this helps :)

Alkali. IF something contains hydroxide ions it is an alkali.
The strength of an acid and alkali is shown using the pH scale which goes from 0 to 14 . pH number of acid is less than 7. and pH number of alkali is greater than 7. that's why the smaller the number the stronger the acid and the larger the number the stronger the alkali. so pH of weak acid is 6 and pH of strong alkali is 14 because if the smaller number shows the stronger acid, the larger number shows the weaker acid. And as larger number shows strong alkali, the pH scale is from 0 to 14; so 14 shows stronger alkali.

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
no
no you do not always need water to see whether something is acid or alkali
Test the pH.
You need to measure the pH of the solution.

its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
only tells you whether it is an acid or alkali.
