So, a Bronsted-Lowry acid is a substance (ion or molecule) that donates (gives up) a hydrogen ion to another substance. A Bronsted-Lowry base is a substance that accepts a proton from another substance. To better understand these definitions, we will take a closer look at the dissociation...

Answer to: Ammonia is a ___. (a) Weak acid (b) Strong acid (c) Weak base (d) Strong acid (e) Salt By signing up, you'll get thousands of...
a teacher is good at chemistry, this is no indication of their ability to teach you or your child. The dissociated molecules are in equilibrium with undissociated molecules. No matter how much water you remove, that will be true. What happens when you mix a strong acid and a strong base...
What is a strong electrolyte? Identify and define the two forms of acid rain. Why are hydrogen bonds the strongest of the intermolecular forces? Give an example of a conjugate pair in which neither species is either a strong acid or base. (Identify the acid and the base.) ...
If the hydrocar bon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added ...

Bases, on the other hand, serve as the doppelgangers of acids: They readily accept protons, tantamount to donating hydroxide ions (OH–) in aqueous solution. The remnant of a dissociated base is called theconjugate acid, and is often a metal cation such as Na+. ...
The conjugate of a strong acid is a weak base. An example of a strong acid is hydrochloric acid, which has the chemical formula HCl. When it's added... Learn more about this topic: Conjugate Acid Definition, Formation & Examples
