Why doesn't sugar solution change the colour of a green universal indicator what does it tell us about the sugar solution?
because its an acid
Is it false that Indicator paper is used to identify acids and bases?
A pH indicator paper can be used to tell if a solution is acidic or basic and the rough pH range can be known
Is it weak acid or strong acid when the position of a reaction lies to the left?
you cant really tell if its strong like that. you need indicator liquid to tell you if its an acid or a base and then tell if its strong by seeing the reaction.
What is The Strenght Of An Acidic Solution?
The best way to find the strength of an acidic solution is to test it with a pH indicator. This can tell you the pH of the solution, which indicates the relative strength of the acid. Acids have a pH of below 7. The lower the number, the more acidic the solution is.
What is the difference between a redox indicator and an acid-base indicator?
Redox doesn't use indicators. It uses the natural colouration of the chemicals involved to determine the endpoint and titre. Acid-base titrations use a pH indicator, as otherwise there is often no way to tell the difference between an acidic solution and a basic one.

Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
What is single ended wrench?
You cant tell the difference with a normal and single handed wrench.....So...Nobody knows

An indicator with Ka equals 1.25 x 10-4 could be used to tell you whether a solution has a pH above or below?

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 do you tell a guy that you like like him but that you cant go on a date because you are 13?
If he likes you and is single, be brave and just straight up tell him

Can anybody please tell how to make a natural indicator using vegetables and flowers and test different household items to distinguish them as acidic or alkaline?
Natural indicators : -Red cabbage solution(juice) -Strawberry solution -Cherry solution -Rose solution You can use any of these as an indicator, and you'll get the same result, here's how : after gaining the vegetable/rose juice, drop some of it on any solution and you'll get the results : the purple cabbage juice turns red when it is mixed with something acidic and turns green when it mixes with something basic.
What is a bite indicator?
A bite indicator is a float used by anglers to tell when a fish has taken the bait.
