We learned about acid and alkali
I have learned that we use acid and alkali everyday in our life without us noticing it.
Acid and alkali is very important, such as that we have to wash our clothes.
We did a couple of experiments on acid and alkali and learned that we can tell if one is acid or alkali by testing it with a Universal Indicator. An acid can turn it into red and an alkali can turn it into blue.
Our saliva is actually acidic.
I also learned about the Ph scale.
A ph scale can go from 1-14
Acidic: 1-6
Neutral: 7
Alkali: 8-14
