Answer:
acidic
Step-by-step explanation:
As concentration is given we can find out pH using -log(concentration)
So input, -log(2.27X10^-3) and it gives us 2.644 (appx.)
according to the pH chart, pH value lesser than 7 refer to acidic substances. pH value 7 means neutral and pH value higher than 7 means basic. As 2.644 is less than 7, so it is acidic.
