Which compound can act as both a bronsted-lowry acid and a bronstey-lowry base?
Ammonia (NH3) --> can become NH2- or NH4+ Water (H2O) --> can become OH- or H3O+
What is the Bronsted-Lowry definition of acid?
According to this concept an acid is a compound which donates a proton (H+). for example, HA + H2O ------------> A- + H3O+ acid water base hydronium ion
Is H2O Bronsted acid or base or both?
H2O can act as both a Bronsted acid and a Bronsted base. As an acid, it can donate a proton (H+) to another species, and as a base, it can accept a proton. The role it plays depends on the context of the reaction.
What is the conjugate base and acid of H2SO3 according to Bronstad-lowry?
The conjugate base of H2SO3 is HSO3- and the conjugate acid is H3O+.
Bronsted and Lowry defined an acid as a substance that protons in a reaction with a base?
The Brønsted-Lowry acid-base theory was discovered in 1923 by two independent people. Jahannes Brønsted Thomas Lowry. In this theory an acid base reaction is one that involves the transfer of a hydrogen ion (H+) from one substance to another. The acid donates the ion while the bases accepts it.ExampleHCl + H2O → H3O+ + Cl- Hydrochloric acid (HCl) is an acid because it donated a proton (hydrogen) to the water creating a hydronium ion.NH3 + H2O → NH4+ + OH-Ammonia (NH3) is a base because it accepts a proton from the water molecule to form ammonium.

What kind of substance accepts an electron pairs?
Lewis acid like Al3+, I2Bronsted-Lowry acids like H3O+But not Bronsted-Lowry bases like OH- or S2- and not Lewis base like NH3 because they can NOT accept an electron pair (octet rule)
Does A base is a compound that produces OH ions in solution?
There are Bronsted-Lowry bases and Lewis bases... Brønsted bases accept protons (H+) and Lewis bases donate electrons... So something like H2O + H2O--> H3O (hydronium) + -OH would mean that H2O is a Bronsted base and acid. You have to look at it in context.

What ions would you expect to find when an acid dissolves in water what ions would expect to find when a base dissolves in water?
This is not a simple answer but nevertheless a complete one according to the Bronsted-Lowry acid / base theory. Acid in water: H3O+ ions from the acid (as proton donor to a water molecule) and the conjugated base anion (negative) as the left over part of the original acid molecule. Example: HCl + H2O --> H3O+ + Cl- Base in water: Most bases are negative anions from basic salts. You'll find in solution (some) OH- ions (together with (base)- ions) and the accompanying metal ion (together with some conjugated acid). Example of acetate base: NaF + H2O --> Na+ + F- + OH- + HF Example of an exception, ammonia: NH3(g) + H2O --> NH4+ + OH-

Which is a conjugate acid base pair in the following equation HS- plus H2O equals S-2 plus H30?
This is a Bronsted question. Hs- is the acid in this which makes H2O a base. Therefore S-2 is the conjugate base and the H3O+ hydronium ion is the conjugate acid.
Does The Brönsted concept describes a base as a proton donor in a reaction?
The Bronsted-Lowry theory of acids and bases states that acids are proton donors and bases are proton acceptors. The easiest example of this is mixing hydrochloric acid (HCl) with sodium hydroxide (NaOH). The acid donates a proton to water, forming hydronium (H3O+) and chloride (Cl-) ions, while the base splits into sodium (Na+) and hydroxide (OH-) ions. Hydronium and hydroxide are what actually "carry" the acidity/basicity, i.e. they are what react in an acid-base neutralization reaction, not the donating ions. The sodium and chloride ions stay stable in solution very well until the solution is evaporated, leaving pure table salt. If exactly equal amounts of HCl and NaOH are mixed, the pH will be exactly neutral (7). Bronsted-Lowry theory applies to more complex situations than the classic model, but it is helpful to remember that ALL theories of acids and bases will work for the simple example I listed above. Arrhenius (classic) acids increase hydronium concentration. Bronsted-Lowry acids are proton donors. Lewis acids are electron acceptors. Bases have opposite effects of acids as described by each of these three theories.
