Ways to identify bases in chemistry?
1-it tastes bitter 2-feels slippery 3- turns from red to blue litmus paper 4-neutralises acids 5-hydrogen ion acceptor 6-it is corrosive
What is the ion present in all basic solutions?
The hydroxide ion, OH-, is present in all basic solutions. It is responsible for the characteristic properties of basic solutions, such as a bitter taste, slippery feel, and ability to turn litmus paper blue.
What are ther characteristic's of bases?
the characteristics of bases: 1) bases have a bitter taste 2) turn red litmus paper blue 3) don't react with metals..The main characteristics of a base is that it changes the color of the indicators. It is a substance in aqueous solution, slippery to touch and tastes bitter.
What is the name of Mn2 plus ion?
The name of the Mn2+ ion is manganese(II) ion.
What is the correct name of the ion mg2?
The correct name of the ion Mg2+ is magnesium ion.
How can you test for hydroxide ion?
One way to test for hydroxide ions is by using red litmus paper. If the red litmus paper turns blue when dipped into a solution, it indicates the presence of hydroxide ions. Another method is to use a pH indicator, such as phenolphthalein, which changes color in the presence of hydroxide ions.
What happens to red litmus paper when it touches base?
Red litmus paper turns blue when it comes in contact with a base. This color change is due to the difference in hydrogen ion concentration between acids and bases.
What color will blue litmus paper turn in presence of a OH ion?
It will remain blue.
What particle in Na-OH causes red litmus to turn blue?
It is the hydroxide ion (OH-) in sodium hydroxide (NaOH) that causes red litmus to turn blue. The hydroxide ion is a strong base and can accept protons from the acidic red litmus dye, resulting in a color change.
What color would the base solutions of OH- ion turn litmus?
The color will be blue.

Is urea acidic or basic?
urea is a basic.If we verify with a strip of red litmus paper it turns blue
What are propesties of bases?
they are bitter in taste they generate hydroxide ion in solution they turn red litmus paper blue
What turns different colors in acids and bases?
indicators - e.g methyl red, methyl orange, phenolphthalein etc.orThose substances are called indicators. They show different colours with different substances. Some common indicators are methyl orange, litmus, phenolphthalein etc.
Chemical test for ammonium ion?
Bases displace ammonia from ammonium compounds, so... 1) Take small amount of the substance that you want to test to see if ammonium ions are present 2) Add some sodium hydroxide 3) Heat gently 4) Ammonia gas is produced if the ammonium ion was present. You can know that ammonia gas is given off if the gas turns damp litmus paper blue.
Why is uric acid called a acid?
Because it is an acid. A way to test if a material is an acid or a base is to test it with litmus if the litmus turns red then it is acid if it turn blue it is a base or alkaline. uric acid turn litmus red. making it an acid.
How could you detect the presence of the NH4 positive ion?
NH4+ can be detected by adding sodium hydroxide, NaOH, and noting the familiar odor of NH3 or by the use of red litmus. The reaction is as followNH4 +(aq) + OH⁻(aq)ß------- NH3(aq) + H2O(I)
