We have had great fun in science club this week.
Last week we identified that some chemicals are acids and alkalis.
This week we tested to find out which chemicals were acids and which were alkalis.
We did not have any litmus indicator, but we created our own.
Can you explain how we made our indicator and why it worked?
Which chemicals were acid and which were alkalis?
Where on the PH scale would you put lemon juice? Where on the scale would you put baking soda?
