Answer:
it was more acidic
Explanation:
changing the pH of the solution and making it more acidic results in the color of the solution changing it from blue to yellow
solution is Bromothymol blue
in a ph below 6 it turns yellow because
a ph below 6 is acidic
a ph above 7.6 its blue because
a ph above 7.6 is basic
Bromothymol blue is made in a basic solution, so it starts out as blue, thus the name 'blue'. It changes to yellow in acidic conditions
