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.
