The link between pH levels and how indicators change color can be pretty tricky.

Indicators are special substances that change color when they come in contact with solutions that have different pH levels.

But sometimes, things get complicated. Here are a few reasons why:

• Changes in temperature
• The amount of the solution
• The presence of other chemicals

If we pay close attention to how we do our experiments, we can make these challenges easier to handle.

Here are some ways to improve our experiments:

• Keep the temperature steady
• Use solutions with known concentrations
• Pick the right indicator that works for the pH range we want to measure

Getting a good grasp of this idea takes careful work. But solving these problems is really important for getting accurate results in acid-base chemistry.
