I need to know how to identify unknown solutions.?

First determine if it is an acid or base, by mixing some acid or base with a sample of it. That can narrow your guesses down.

Another trick is to mix up some of your OWN solutions and see how they react with other known chemicals.---then apply what you learn to the unknown.

common indicator is a pH indicator that transitions by numbers 3-12 (on the pH chart) to point the acidity or alkalinity of suggestions. indexed here are the colorings that time out the acidity of a answer, after including UI: a million. Very acidic - purple 2. Acidic - Orange/Yellow 3. independent - green 4. undemanding/base/alkali - Blue 5. Very undemanding/base/alkali - purple purple Litmus Paper turns blue while it extremely is dipped in a answer of pH 8.3 or greater (greater beneficial alkalis), and Blue Litmus Paper turns purple while dipped in a answer of pH 4.5 or much less (greater beneficial acids) this might help u to classify and locate the acceptable answer a million. Sodium hydroxide types a stable alkaline answer while dissolved in a solvent which comprise water 2. hcl is extremely acidic 3. barium is undemanding
