Why pH paper become reddish?
Components of pH paper react with acids or bases.
What is the pH level in Tums?
Tums react with acids from the stomach.
Do buffers react to acids and bases to keep pH in a?
Buffers are used to maintain the pH constant.
Will strong acids turns universal indicator paper red?
yes strong acids will turn ph paper red
How can you test for acids and bases?
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
How do you differentiate between an acid and an alkali?
An acid has a pH level below 7, whilst an alkali has a pH level above 7. Acids contain H+ ions and alkalis consist of OH- ions. Acids turn litmus paper red, alkalis turn it blue. When acids react with metals they form hydrogen and a salt. Acids a sour to taste. Alakalis react with acids to form salt and water, a reaction called neutralisation. Alkalies feel soapy to touch. All alkalis except ammonia will react with ammonium compounds, driving ammonia out.
Is it true buffers are weak acids or bases that can react with strong acids or bases to prevent sudden changes in pH?
TURE
How can you distinguish among acids bases and neutral substances?
The simplest method is to determine the pH with a pH-paper or a pH-meter.
Why alkalis are sometimes describe as the opposite of acids?
Alkalis (bases) react with acids to neutralize them, so in one sense, they can be considered as "opposite" of acids. Bases produce pH values >7 and acids produce pH values <7.
Can water affect the color of the pH paper?
i don't know that's why i asked you ... no, because pH paper only detects Acids and Alkali substances, water has a pH of 7 because it is neutral, but has no affect on pH paper :)
What is the difference between an acid and a base in water?
An acid in water will react with the water to form H+, which are acidic ions. Acids will also turn litmus paper red, and have a pH less than 7. A base in water will react with the water to form OH-, which are basic ions. Bases will also turn litmus paper blue, and have a pH greater than 7.
Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
