guys what would u select and why
question is shit bc it's v ambiguous w what they want u to find. it says confirm the findings that it's acidic so i'd say litmus but it also says they used the flower indicator to 'determine the acidity of an unknown solution' which kinda hints at them knowing it's acidic so u wld go methyl orange? but i'd say litmus is the most correct

There's something i realised I don't understand. How does the Carbonic Acid Hydrogen Carbonate buffer resist additions of strong bases. Like the OH reacts with the H2CO3, but wouldn't that cause the system to shift left, increasing pH anyway?
Good to be self aware
