plez help me to discusse my obseverion,I just did a draft,let me know if am doing it good or if am missing anything eles..u could also add on it...thanks
-Aim:To determine the pH of some household products
Eleven different household substances was given. Universal indicator was used to identify the pH of each household substance.One by one household was poured into test tubes and a small piece of universal indicator was droped into the particular household substance,and then perform it changed.As obsevered closely three substance was very acidic,four was neutral and four was basic.Mostly the lightier liquid changed to acidic such as the bleach,rubbing alcohole ect..and the heavier liquid such as milk (liquid),disinfectant.

Bleach is alkaline, not acidic.
Rubbing alcohol is neutral, not acidic.
Milk is neutral to very slightly acidic, not alkaline.
Disinfectant? This depends on what it's made from but if it's alcohol based, it's most likely neutral. Lysol (phenol) is weakly acidic.

I think the rubbing alcohol (isopropyl alcohol), should have been closer to neutral.
also the "weight" of the liquid is not a factor. It may have been just a coincidence in the items you tested

I ASSUME YOU were doing the old litmus paper test. you have to have a reference indicator to compare to the strips to estimate how caustic or acidic it is. didn't they give you a text, a lab book or lab materials to get started? were you paying attention when they handed out the ahhhh, books? go back to school tomorrow and either talk to the teacher or prof and if you don't understand what i am saying with his help, forget chemistry. study typing or indusrial sewing or fast food preparation. lol
