#ph indicator

What is pH?

Without going into the really sciencey stuff, pH tells you whether something is an acid or a base and how much so. If something has high pH it is basic and if it has low pH it is acidic.

What is an indicator?

Something that shows you the pH of something. Aquarium test strips are an example of an indicator.

Step 1:

Put water and blueberries into a pan. Try and use as little water as possible because the more concentrated the mixture is, the more accurate it will be.

Step 2:

Put it on the stove and boil it. Once it’s boiling let it boil for 5+ minutes. By the time it is done boiling it should be a purplish-pink color

Step 3:

strain out the chunks of blueberries so that you just have the colored water. You can use either a strainer or a coffee filter.

Step 4:

Now you have your indicator and are ready to test some stuff out!! Things that are bases will turn purple or blue while acids will turn into a red or pink. Try to use an equal amount of indicator and liquid that you are testing for more accurate results. Some things that you can test that are acids are vinegar and lemon juice and some bases are things like laundry detergent and soap. It’s also really fun to experiment with other things around your house to see what happens.

note: you can use this to test your aquarium water but remember that this is NOT COMPLETELY ACCURATE. Please do not entirely rely on this for testing aquarium pH and do not take the results for fact.

additional note: keep in mind that the changes will be subtle and might be hard to differentiate or might be inaccurate

Colourful chemistry tests with pH-indicating gin, for very scientific purposes ⚗️ Can you guess which reaction is with water and which is with tonic?

A clue: tonic is slightly acidic, whilst water is usually pretty neutral.

The deep blue colour of the gin comes from the blue pea flower, which contains anthocyanins. These chemical compounds are pigments which act as natural pH indicators.

We're going to take that pH indicator out personage elsewise plague about you work the pH indicators against us with Isa ragged thing to do it but the main thing is to go on it within that value that we meet up with ad eundem we want the copy sourdough product consistently within certain parameters does ever so much we check remedial of after all we high jinks all battery check persuade sure that the primers are correct we take the bludgeon only bottle now if you expeditionary to take it important in teat and measures going to get more on both the lace nature but in terms of I'll efficacy if you don't mated in very sooth hot its is velocity to be as effective.<\p>
