Red cabbage experiment

hello everyone. 

I want to find out how to tell if something is an acid.

method:

equipment:

beaker

hydrochloric acid

soduim hydroxide

red cabbage

hot water

dropper

test tubes

different samples for testing

instructions:

gather equipment

rip the cabage into small peceis

put them into a beaker 

add hot water

after a little boiling it should turn vilot

after it does get the dropper and suck up sonme of it

then put in a test tube and out deffrent amounts of the hydrochloric acid then soduim hydroxide.

result:

this is our science. In this science class we are doing chemistry. This time I have learnt on how to test if something is more an acid or a base. we tried this with a red cabbage and when we put acid or  base in. it could change colours with what we put in, if it was more on the acid side then it would be red, orange, and green. if the base it would be blue vilot and indigo. the acid was hydrochloric acid soduim hydroxide. Acid can be nutaralised by bases and that is why it changes colour.
