Last week for science we did indicators. It was fun to experiment with the 3 different liquids. We used the test tubes for this experiment. I enjoyed this experiment because I got to learn something new about indicators. Acid turns red when you put it in Hydrochloric acid, acid is found in something like vinegar, lemons and other citrus fruits. What is an alkali? Alkali turns blue when you put it in sodium hydroxide. What is an indicator? something that indicates the level of something. The indicators we used were cranberry juice, tea and turmeric. The 3 indicators, changed colour (went darker) when we put the alkali in, when we put the water in it was the same, when we put the acid in the went clear. Why are indicators needed in science? Indicators are needed in science so we can find out the different acids and alkalis. What was hard, using the different indicators was hard. What was easy everything else was easy. I enjoyed doing this experiment because I learnt a lot.
Thanks for reading please leave me some feedback.
Universal Indicator/Blue is alkali, green is neutral, red is acid.
