Ammonium hydroxide ionizes as follows: nhoh(s) nh4 "(aq) + oh'(aq). if an excess of ammonium salt, such as
nh4cl (which ionizes to give nha (aq) ions) is added to the equilibrium shown above, you could predict that the result
will be to
decrease the concentration of nh4oh
cause the temperature to greatly increase
decrease the concentration of oh
increase the rate of the reaction to the right
not disturb the equilibrium

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
