Discussion The color change of a pH indicator is caused by the dissociation (the breaking apart) of the H+ ion from it.
An acid gives a proton to the indicator. When two or more substances combine, they create one or more new substances. when you put the universal indicator in the test tube put 10 drops of
universal indicator and then put acid and base if you want it more darker put Basin if you want it to put back as the colour that you had it for acid in it the colours and pH colours re orange yellow green blue Indigo violet. it is the hardest to get orange yellow and green they're the hardest you gonna add the right amount in. it was so fun to do it and I hope you enjoyed it.
