Some examples of bases in mathematics include the decimal system (base-10), binary system (base-2), hexadecimal system (base-16), and the octal system (base-8). Each of these bases represents how numbers are represented and counted in different ways.
1 molar Hydrochloric acid has a theoretical (actual is pretty close too) of 0. The pH is defined as the negative logarithim to base 10 of the Hydrogen ion concentration. So - log10[1] = 0 Battery acid being stronger than that has a pH of zero (actually slightly negative).
Answer: KA = 3.3*10-4At first calculate KB ,supposing that this is a monoprotic weak base (B-):[OH-]=1.0*10-(14-7.94) = 1.0*10-(6.06) = 8.7*10-7 and cB = 0.025This filled in, using KB = [OH-]2/ cB to get:KB = [8.7*10-7]2 / 0.025 = 7.59*10-13 / 0.025 = 3.0*10-11Finally get KA by using:KA*KB = KW = 1.0*10-14 (in water, at room temperature)this results in KA = 1.0*10-14 / 3.0*10-11 = 3.3*10-4
A pH of 10 is a base. Anything higher than 7 is a base and anything lower than 7 is an acid. 7 is neutral.
There is no particular pH that a buffer will be, it depends upon the buffer. It can be any pH. What a buffer does is to cause the pH of the solution to change less than it would without the buffer when acid or base is added to the buffered solution.
Hydrazine can act as both a Lewis base and a Lewis acid. As a Lewis base, it can donate a lone pair of electrons to form a coordinate covalent bond with a Lewis acid. As a Lewis acid, it can accept a lone pair of electrons from a Lewis base to form a coordinate covalent bond.

They are medium-strong bases. Anything with a pH level over 7 is a base, 8 being a weak base and 12 being a strong base. Anything Below 7 is an acid, 6 being a weak acid and 0 being a strong acid.
Helium does not form any compound.
Base refers to the foundation or primary ingredient of something. In chemistry, a base is a substance with a pH higher than 7, such as sodium hydroxide. In mathematics, the base of a number system determines how numbers are represented, for example, base 10 (decimal system) or base 2 (binary system).
it is a compound molecule , and even i know a sixth grader

Strongest (conjugated) Acid:hexa-Fluoro-Antimonic Acid (HSbF6 or HF.SbF5), pKa = -25It is conjugated to the base: SbF6-Classified as a "Superacid". This acid will donate proton to C2H4 to form a ethane-carbocation. Compare: pKa(HClO4) = -10, HClO4 does not react with ethene.
