The shape of the molecule is trigonal planar.

Molecular Geometry of Methylamine (CH3NH2) As there are two central atoms in Methylamine (CH3NH2) the molecular geometry for both will be different as the bond angles are different. In the case of carbon mainly targeting -CH3, its molecular geometry will be tetrahedral as the forming bond angles are 109.5°.

CH3NH3+ is the conjugate acid of CH3NH2 which is called methyl amine. Since CH3N3+ is an ion it gets the -ium ending so it is called methyl ammonium ion. As a side note NH3 is ammonia and NH4+ is an ammonium ion for the same reason. 1.

This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine. It is sold as a solution in methanol, ethanol, tetrahydrofuran, or water, or as the anhydrous gas in pressurized metal containers.

why CH3NH3Cl is a strong acid?

CH3NH3^ + – CH3NH2 is a conjugate acid base pair.

Re: Determining relative strength of acids and bases CH3NH3Cl is an ionic compound, consisting of CH3NH3+ and Cl- ions. The overall salt does not donate protons, the CH3NH3+ ion does (to form H3O+) when the salt is dissociated in water.

NaHSO4 is also an ‘acidic salt’ as its its aqueous solution is distinctly acidic in nature. Usually, an acidic salt is a salt of strong acid and a weak base which produces H+ ions by interaction with water molecules (hydrolysis).

Acid-Base Character For instance, in sodium hydride (NaH) the hydrogen has a -1 charge so it is not an acid but it is actually a base.

Monopotassium phosphate, with the chemical formula KH2PO4 or H2KO4P, is neither a base nor an acid but a salt.

Sulfurous acid, H2SO3, is a weak acid capable of providing two H+ ions (pKa1 = 1.9, pKa2 = 7.0).

Iron(III) bromide is the chemical compound with the formula FeBr3. Also known as ferric bromide, this red-brown odorless compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds.

Barium nitrate is a highly water-soluble crystalline source of barium. This compound is slightly acidic due to its acidic pH. This metal nitrate is an inorganic salt of a metal cation and nitrate anion.

Potassium carbonate (K2CO3) is a very weakly acidic compound (based on its pKa).

Chemistry. determine the pH of a 0.116 M Ba(OH)2 solution at 25 degrees C. i keep getting 13.06 for this answer, but the answer is 13.37 :S.
