How would you measure the pH of an unknown colourless solution?

Sticking a piece of litmus paper into it would be the first step in my estimation. See if it's base or acidic. If it is strongly one or the other, don't touch it with bare hands.

What is the color of aluminium chloride solution?
You geek, why would you want to know that freak show
Hydrochloric acid potassium carbonate?
Because hydrochloric acid is a clear solution and potassium is a solid white powder the observation would be: a colourless, clear solution is add to a solid white powder which formed a solution and produced orderless, colourless gas. equation: 2H+(aq) +K2CO3(s) ---> 2K+(aq)+ CO2(g)+ H2O(l) NOTE: observations are what you actually see, therefore you would not be able to tell is the colourless gas was carbon dioxide or that water was present in the solution.
Why does the indicator goes purple in sodium hydroxide solution?
The most common one would be phenolphthalein which is colourless in acid and turns a pink-purple in base
An unknown substance is added to a solution and the pH increases The substance is best described as what?
The unknown substance would have to be a basic solution. At least more basic than the initial solution. The pH scale ranges from 0,Most acidic, to 14, Most Basic. If the pH of your solution increases when the unknown substance is added, then it would lead you to believe that the added substance is of a basic nature.
Are solutions always colourless?
This is commonly used when describing liquids. "Clear" in this context means that you can see through the liquid, so if you put a penny (for example) in a cup of this liquid, you could still see the penny. "Colourless" would mean that the liquid was the same colour as water. Clear but not always colourless means that the liquid may have a tint (so it may be blueish or greenish or some other colour) but you can still see through it.
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
What would you see when ozone is bubbled through aqeous acidified potassium iodide?
from colourless(solution) to brown(solution)

If both sulfur dioxide and carbon dioxide dissolve in water-what color would the solution be?
SO2 is less soluble in water... but solution of SO2 and CO2 will be colourless...
What does lead do in hydrochloric acid?
Lead will form Lead(II) Chloride in a HCl solution, but if exists a higher chloride ion concentration, it would form a soluble complex and a colourless solution.

Colourless solution in the reaction between sulfuric acid and sodium hy droxide?
You'd wind up with a solution of sodium sulfate and some water formed, along with any excess reactant. The solution would be clear and colorless.
How zinc oxide reacts with excess sodium hydroxide?
Zinc salt will form complexes of sodium zincate which is colourless and a clear solution would be observed

Describe how you would measure PH of an unknown liquide?
Add universal indicator.
