Hi Addyson
ReplyDeleteWell done on completing another science blog post. You could have improved this post by telling me what you learnt about hydrogen.
It's great that you can work with a buddy to learn the science behind the pH scale. I hope that you will enjoy our next experiment about the pH scale.
