The best material is NOT!!! plastic its news paper!!
i never use paper towels, for it leaves lint behind..the best thing to use, is newspaper..I know it sounds crazy, but it completely works and you won't waste alot of money on paper.
Water is considered the universal solvent.
Litmus paper or universal indicator are the best ways.
Jjjjj
an indicator is capable of determining if a substance is basic or acidic or neutral. if you are just looking for if it is a basic or acidic. then you could you could use red litmus or blue litmus. if you are looking for the pH of a substance try using: red cabbage indicator phenolphthalein i hope i answered your question!
use litmus paper SI
The most elementary one is Litmus Paper. It measures red for acid and blue for alkali. Then there is UNIVERSAL INDICATOR, a liquid, This will slowly change colour from red(very acidic (pH 1)) to green(neutrality) (pH 7) to indigo (Alkaline )PH14)) Theren there is a pH meter , which is an electronic probe put into the solution to read off the pH .
the best way would be 2 use litmus paper. use the color coding on the box but usually blue is for base and red is for acid.
A pH meter gives a direct reading which is great when testing wine or soft drinks. Litmus paper will go red in acid or blue in base. An acid will liberate carbon dioxide from chalk - a base will not You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic. Turmeric indicates acid by turning strong yellow. Base is indicated by red. Phenolphthalein indicates bases by turning red or purple. Acid is indicated by no color.
No, not always. Some indicators are better suited for certain ranges; UI will provide a rough indication across a huge range, but other indicators can be more accurate across a small range, and this is when they are used.
An indicator changes colour in the presense of acidic and basic solutions. It will be one colour for acidic solutions, and another color for basic solutions. With some indicators, the intensity of the color increases with the intensity of the acidity of 'basic-ness' of the solution. Cabbage is a natural indicator. An Acid turns pink and a base turns greenExamples of acid-base indicators: 1.) Litmus Paper acidic solutions will turn the blue litmus paper to red while basic solutions will turn the red litmus paper to blue2.) Congo Red basic solutions will change the color of the entire solution into blueThere are many indicators, some of them are :-Solution of red cabbage, or rose flower, strawberry, or cherry.These turn lighter(yellowish) in the presence of an acid, and more darker(violet) in the presence of a base.-Phenolphtaline : It is a chemical solution that remains colour-less in the presence of an acid, and violet in the presence of a base.-Red/Blue Litmus Paper : the RLP turns blue in the presence of a base, and the BLP turns red in the presence of an acid.And finally you can use a pH meter or pH paper to indicate the indentity of the solution.
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.

The best indicator for current weather is a barometer because it tells you if there is rain or if it is sunny.
