Which indicator could be used to identify a neutral solution?
there is no such indicator.the only way is to add the acidic and basic indicators ,if it does not change the colour of the solution then it is neutral.
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
Why do you keep checking the pH when mixing a alkali and a acid?
generally if you mix an acid or an alkali together, it is for titration, whereby you want your result to be neutral solution. The only way to check if a chemical solution is neutral is by checking the pH and thus can be done by the indicators ie: universal indicator, methyl orange, screened methyl orange, bromythyl blue, etc
What is pH of potassium sulfate granular?
Granular potassium sulfate does not have a pH. A pH value can only be given to a solution.
What does an indicator have to have to be an indicator?
An indicator has to be able to change colors as the pH of the solution approaches ithe indicators pH range. For example, universal indicator starts out as a yellowish color in an acidic solution, then as it grows more neutral(more towords 7) it becomes a greener color, and as it grows more basic, it starts to become a blue color. Universal indicator will give you an indication of HOW acidic or alkaline a solution is, depending on the exact color. Litmus can only turn red or blue and can't distinguish between differing amounts of acid or base

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

Distilled water is about the only completely neutral solution What is its pH?
7
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)
How does Lugol's solution work as an indicator?
An indicator is a substance that changes colour in the presence of another substance. Let say inside the beaker are substances of both glucose and starch. The glucose and starch are of same colour. By injecting the lugol's solution into the beaker, the lugol's solution changes colour in the area of where starch is, while no colour changes in the presence of glucose. Thus, by using the Lugol's solution which only acts as indicator for starch and not glucose, we could tell part which area floats around with glucose and starch substances. Lugol's solution works as an indicator because it will stain starches due to iodine's interaction with the coil structure of the polysaccharide.

How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
What will happen if you pour starch indicator solution into the cell and filled the beaker with starch and glucose solution?
The starch indicator solution will diffuse out of the bag (cell) into the beaker, changing the color of the starch solution to a blue, purple, or black color (assuming that it's iodine). The color of the indicator solution inside the bag will not change, because only the glucose can diffuse into the bag, but the starch cannot diffuse into the bag.
Which substance is neutral?
Generally a neutral substance is called an inert substance.
A substance with equal numbers of H and OH ions is an alkaline solution?
No, only exces of OH- gives you an alkaline solution and exces of H+ gives you an acidic solution. When they are EQUAL then the solution (water) is NEUTRAL, pH= 7.0
