Calculate the pH of a 0.3 M solution of a weak acid, AH, for instance CH3COOH, and 0.15 M of a salt derived by its conjugate base, ANa, like CH3COONa. The acid dissociation constant, Ka , is 1.76e-7. What is the pH if 32 mL of 0.103 M of a strong acid, like HCl, is added to 100 mL of the buffer solution? What if a strong base, like NaOH, is added with the same ammount instead ? answers

dishwashers don't have rights

explanation:

dishwashers are meant for one thing and one thing only: dishwashing. they belong in the kitchen making sandwiches and cleaning up for the man of their household. if your dishwasher starts acting up just slap it and wait a minute.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
