What else can I help you with?
What colour should sulfuric acid be after universal indicator is added?
Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.
What colour does acid rain turn universal indicator?
It should turn the UI to a light yellow because it is a very mild acid. It has a pH level of around 6. Whereas a strong acid like Battery Acid (pH 1) would make it a red.
What shows whether something is an alkali or acid?
You can use indicators (liquid or paper). Universal Indicators (UI) are the best, as with them you can tell if something is acid, neutral or alkali, depending on the colour (there will be a colour indicator). However, you can also use red and blue indicator, but they are less accurate, as although they might be acid (or alkali), they might be neutral as well, so I suggest you use UI. Hope this helps :) Source: Science lessons!
If you add ui to sodium hydroxide what is the colour turns to?
Adding iodine to sodium hydroxide will result in brown color due to the formation of sodium iodide and sodium hypoiodite.
Is the reaction between sodium hydroxide and hydrochloric acid a redox reaction?
NO!!! It is a NEUTRALISATION reaction. For a REDOX reaction there would be a change of electrons / e.g. the sodium ion (Na^(+)) would either gain or lose electrons. In the given reaction the sodium cation does NOT gain or lose electrons but remains as Na^(+) Similarly the chloride anion. Cl^(-) Chemically the reaction equation is NaOH + HCl = NaCl + H2O Ionically this eq'n becomes [Na^(+) + OH^(-)] + [H^(+) + Cl^(-)] = [ Na^(+) + Cl^(-)] +[ H^(+) + OH^(-)] Notice all the ions present have neither gained nor lost electrons. Their ionic charge remains the same. So it is NOT a redox reaction. No ion has been oxidised nor reduced. However, on applying universal indicator (UI), the NaOH would be BLUE, The HCl would be RED . On mixing the alkali and the acid together the UI would be GREEN. (indicating neutrality. Also the fact that water is produced indicated that the acid and the alkali have neutralised each other.
What colour would a UI be in strong acid?
The answer is...RED!!!!Strong Alkali is DARK BLUE!!!
You add UI to lemon juice what colour is the mixture?
The color will be a fairly strong red as it is a very strong acid in the pH scale.

Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.
How do you measure the acidity of acid rain?
You add universal indicator and then compare the colour it turns to an example ph scale. The redder the Ui the more acidic it will be, if it is green it will be neutral and if it is blue/purple it will be alkali.

6.7 pH is what color?
Using a UI indicator solution, or UI paper, pH 6.7 corresponds to a yellow/green colour

When was JQuery UI created?
JQuery UI was created in 2006.
