what is ionization
= =
The literature value for the ionization constant (KB) of water (H2O) is approximately 1.00 x 10^-14 mol^2/L^2 at 25 degrees Celsius.
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
So NH4Cl(s) -----> NH4+(aq) + Cl-(aq). As NH4Cl is ionic you can assume it is a solid. Since H2O is polar it reacts with the NH4Cl ion in a way which allows it to dissociate the ion. The oxygen is slightly negative while the hydrogens have a partial positive charge. The negativity of the oxygen in H2O causes the positive charge of the NH4+ molecule to cancel making it no longer attracted to the Cl. The hydrogen in H2O will do the same to the Cl. Once this happens you will have the products stated above in the reaction equation. NH4+ will further react with the water. NH4+ + H2O ---> NH3 + H3O+ . H3O+ is produced rather than OH- because NH4+ is acidic and therefore will donate a hydrogen. Note that because NH4Cl fully dissociates, you do not add in the + H2O in the first equation.
H+(aq)+OH−(aq)→H2O(l)
C6H5N2 Cl (aq) + H2O(l) C6H5OH(aq) + N2 +HCl(aq)
The second ionization reaction of phosphoric acid (H3PO4) with water is: H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)
HCLO3--->H3O+Clo3 H3O--->H+H2O H2O--->2H+O
The equation for the ionization of ethylamine in water is: C2H5NH2 (ethylamine) + H2O → C2H5NH3+ (ethylammonium) + OH- (hydroxide)
The equation for the ionization of CO3- with water is: CO3- + H2O → HCO3- + OH-
hydronium ion and the hydroxide ion h2o + h2o <--> h3o+ + oh-
The literature value for the ionization constant (KB) of water (H2O) is approximately 1.00 x 10^-14 mol^2/L^2 at 25 degrees Celsius.
HCl (aq) + H2O (L) ---------> H3O+ (aq) + Cl- (aq)
Not sure if this is what the question is but it's a typical example of structural isomerism in coordination complexes, related by interchange of ligands inside the coordination sphere for those outside. Usually supplied as green solid [Cr(H2O)4Cl2]Cl.2H2O] (assuming with relevant geometric isomers) Solutions turn blue green in water as [Cr(H2O)5Cl1]Cl2.H2O] formed.
The "l" subscript on H2O signifies that water is in its liquid state at room temperature and pressure.
The corresponding reaction to the equilibrium is; H2O(l) <-> H+(aq) + OH-(aq) or another interpretation is; 2H2O(l) <-> H3O+(aq) + OH-(aq)
You need to look up 'positive hydrogen ions' in some form of chemistry book?
Process C (H2O l -> H2O g, 0.010 atm) is the most spontaneous at 298 K because it has the lowest pressure of water vapor, favoring the vaporization of liquid water. As pressure decreases, the entropy change due to the increase in disorder upon vaporization becomes more significant, driving the process towards spontaneity.
