What is a substance that tastes sour AND TURNS BLUE LIMYTUS RED?
well as we know if we want to test a substance to see if its a base then we use red litmus paper and for an acid we use blue litmus paper. So if we are using blue litmus paper… that means we are obviously testing to see if we have an acid right? So if we see it turn pink then that means that are substance is an acid but it is not very strong and also has some of a base to it. If you want to see what i mean look up a PH scale. Hope this helped. :)
Just to remember: Base > Blue and aciD > reD
An acid will turn the blue indicator to red.
The Compounds that give fruits and vegetables their red color are very sensitive to acidity. As long as they are acidic they stay red, but when they become non-acidic th…ey turn blue. When you saute red cabbage, the acids evaporate off and it can turn blue. All you have to do is add lemon juice or vinegar to bring back the bright red color.
Acidic less then 7
blue because higher in ph scale red in 0 to 7 7 is nutraul and 8 to 14 is blue
Bases turn red litmus paper blue. Alkali (ammonia) Alkaline
Sodium hydroxide or any other Alkaline substance an alkiline is a corrosive substance that turns litmus blue ;)
Acids turn both red and blue litmus paper red. Bases turn both red and blue litmus paper blue. Neutral substances (water) turns red litmus red and blue litmus blue.
Well, the whole thing is very complicated. The asorbic acid in sour, compliments the falic acid in other sour foods. It may seem more sour to you if you taste sour on sour, bu…t it is just your taste buds reacting to two different chemicals. Both chemicals combined make it very easy to be tasted, and sometimes disliked. When you taste sour on salty it's harder to taste. One ingredient in salt, called cottonseed extract, mainly counteracts most asorbic and falic acids. So, in most salty foods it's harder to taste sour things.
A base/alkali substance will turn litmus paper blue.
Any thing that goes to the middle sides of your tongue. Specially War Heads (TM) and lemons
There are a few different ways you could test for sour and bitter substances without tasting them. You could test for the presence of elements that make something sour or …bitter for example.
