In an acid-base titration, how would you monitor the progress of the experiment and know when it was completed? A. Continue the reaction until you have added an equal volume of acid to the base.
B. Add 1 ml of acid at a time to the base and monitor with pH paper until it is neutral.
C. Use indicator solution which changes color when enough acid is added to react with all the base.
D. Place a thermometer in the flask and continue adding acid until a temperature change is noted.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

girl imma just put my comment here because i need a couple point okurrttt

consider the reaction below.

 no rx

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

0.42

2.4

24

the answer is d.) potassium
