The lower the PH, the higher the acidity.
It will say on the bottle or website if it is NOT tested on animals. If it doesnt say anything it probably is tested on animals
Have it pressure tested, the intake gaskets have probably failed.
This solution is acidic.
Tresemme is not tested on animals animals it says on the back of the bottle u by not tested on animals
Starch, I think, because iodine solution is the test for starch.
One possibility is a 10% solution of hydrochloric acid.
Iodine solution turns blue/black
No probably not No probably not
A reference solution was used in order to see what reaction happens between a test reagent and a solution with a high value of the ions being tested. A blank was used to show that there is no reaction when the ion being tested for is not present in the solution.
It means that the substance tested is neutral.
By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
You can't tell that a mixture is a solution to anything until the mixture is thoroughly chemically tested and proven.
