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.

What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
In the titration of NaOH and C2H2O4 using phenolphthalein, the colour change will occur at the endpoint when the solution transitions from pink to colourless. Phenolphthalein is pink in basic solutions and colourless in acidic solutions, so once all the oxalic acid is neutralized by the sodium hydroxide, the solution will turn colourless.
What color does phenolpthalein turn in the presenc of an acid?
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
What colour is phenolphthalein when soda is added?
As soda contains carbon dioxide, it's actually a dilute solution of carbonic acid, hence phenolphthalein remains colourless.
The color of methylorange indicator in a neutral solution?
an universal indicator paper tells you how acid or how alkali it is acid - red alkali - blue neutral - green
What is the colour of helium at room temperature?
Helium is a colorless, odorless gas at room temperature.
What is the colour of aluminium sulphate solutions?
aluminum sulphate is colourless
What is the colour of an aqueous sodium bromide solution?
Colourless solution. most coloured solutions contain transition metal ions
What is a indicator of acid?
All acidic solutions are colourless in phenolphthalein, pink in methyl orange solution and turns blue litmus paper into red.

What is phenylthalein?
Phenolphthalein is a chemical compound with the formula C20H14O4 (often written as "HIn" or "phph" in shorthand notation). Often used in titrations, it turns colourless in acidic solutions and pink in basic solutions. If the concentration of indicator is particularly strong, it can appear purple. In strongly basic solutions, phenolphthalein's pink colour undergoes a rather slow fading reaction and becomes colourless again. In other words, the molecule has four forms: {| ! Species | In H2In In2− In(OH)3− ! Structure ! Model ! pH | < 0 0−8.2 8.2−12.0 >12.0 ! Conditions | strongly acidic acidic or near-neutral basic strongly basic ! Colour | orange colourless pink to fuchsia colourless ! Image | The rather slow fading reaction that produces the colourless InOH3− ion is sometimes used in classes for the study of reaction kinetics. |}
