<p>a question I do have. don't worry, I'm just lookiing for a short explanation, no math, just processes.</p>
<p>if given x amount of test tubes, and I have to order them by their basic/acidity level, and the only liquid i have at hand is phenolpthalein, what do I do? </p>
<p>2nd question coming later this week!</p>
<p>thanks a bundle :p</p>
<p>Well isn't that an indicator (sp?) so if you put it in and it turned red it'd be an acid, if blue a base, if green neutral. That's how it should work.</p>
<p>Well phenolpthalein is an indicator, and you would have to titrate the solutions. It only works in certain pH's where it will change that solution to I believe a pinkish-purple color.</p>
<p>With a slightly basic solution...around maybe a pH of 8-12 lets say, it will appear pink in the solution. At solutions more alkaline than that, it will looks more purple. In acidic solutions, there will be no color at all.</p>
<p>Yeah...then you mix the various solutions together two at a time and titrate like I told you online. :)</p>
