Does anyone have a specific way of remembering which indicator you use for which reaction? I know which ones to use but just need a way of remembering it if that makes sense!

Hi!
Well you know how If it's a strong Acid you'd use Methyl orange right? Well personally, Orange juice (The actual juice of an orange) tastes quite sour right? so like acidic right? So you can instantly realize, "Oh Strong acid, Hmm methyl orange"
And then for the Phenolphthalien i would just use a process of elimination , so then we know its used for a strong alkali!
Sorry if i don't make sense! |:
good luck for your exam! xD
