You can measure the pH value, if the value is below 7, then it is an acid. (1 being the strongest, 7 being neutral.)
There are also some indicators, phenopthalin (think that is what is it called)
which will turn purple, when poured into an acid.
The acid tells you wether or not te mineral contains lime. Drip any (strong) acid onto the mineral, and if it starts bubbling, the mineral contains lime. It's often used by people who have a fishtank, as rocks which contain lime are bad for most freshwater fish.

You can tell if something or someone will grow into something great by watching it early in childhood. Conversely, you can also tell if someone or something will never be great based on how they are early on.
they both tell you about something
yes it does
Test the pH.
An indicator, for example Litmus.
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
you get a scale like this
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
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 :) Source: Science lessons!
Only an acid releases carbon dioxide (gas bubbles) from bicarbonate.
The pH of the solution can tell if it is acidic or alkaline. For acids, pH will be 1 to 7 and for alkaline it will be around 8 to 14. pH of 7 is for neutral solution.
Add an alkali substance to it, such as chalk, if it is an acid it will "fizz" and release carbon dioxide. You could also test with Litmus Paper or Universal indicator.
add phenolphathalein to both.it will be colourless in dilute acids and pink in dilute alkali
A wasp sting is alkali, so if you put an alkali on it, it would not work. To neutralise the sting, you would have to use something acidic, like vinegar, also known as acetic acid. If you want to know more, then I can tell you about bee stings. Bee stings are acidic, so you shouldn't put something acidic on it. Try something alkali, like baking soda, or ammonia. That should help to neutralise the bee sting. Hope that helps x
One way to determine if a substance is an acid or alkali is by using pH paper or a pH meter to measure its pH level. Acids typically have a pH below 7, while alkalis have a pH above 7. Another way is to observe its chemical properties, such as its reaction with indicators like litmus paper (turns red in acids and blue in alkalis).
