pH Indicators Lab Practice

In conclusion the most accurate indicator was the one that we used last, with the gatorade, milk and soda. This was the most accurate indicator since it had four different sponges that absorbed the liquid and then the pH was decided by the 4 colors of the different sponges instead of just one or two. After this indicator the next more accurate one was the one with one sponge since this one not only showed you if it was an acid or a base it also told you roughly the pH it had. At las the least accurate one was the drops wince this only told you if it was a strong acid, a strong base, or an acid or a base. I really liked this experiment since it showed me both how old scientis used to get the pH and how new scientist do this.
