Still mixing up
indicator colours?
Try this question. Then see how three letters can help you remember the answer.
LET’S WORK IT OUT
Pick your answer.
Then check the reason.
It’s fine if you’re unsure. The useful part is knowing what to remember next time.
After this question, you’ll try a second one with the memory cue hidden.
Remember ROY.
Red → Orange → Yellow, as pH increases.
The detail to watch: methyl orange is yellow in neutral water too. Orange does not mean neutral.
A short website version of Hack 32. The PDF includes the concept, exam questions and worked explanation.

FROM YOUR TEACHER
Hi, I’m Mr. Goh.
I teach IGCSE Chemistry and Biology. I created ChemiHack to help students understand difficult concepts, avoid common mistakes and answer exam questions with the right scientific keywords.
My suggestion: try the question first. If you get stuck, check the explanation or watch the lesson. Then close it and have another go. That last step matters.
CH Goh
Looking for online classes too?
I also teach IGCSE Chemistry and Biology online. Send me your school year and the topics you’re finding difficult, and ask about current times and fees. You can use ChemiHack without joining a class.
