To determine the concentration of Fe (aq)2+ by a redox titration, we could use an acidified
standard solution of
A. Sn2+
B. Pb2+
C. HCl
D. H2O2
I know the answers H2O2, but i don't know how to get it. How doe redox titrations work?
I am a bit confused when doing questions about 2 masses connected by a pulley system.
Sometimes i get the right answer when i use just one of the masses to get the acceleration but other times i have to use both masses to get the correct acceleration.
How do you know when to use just one...
Thanks for the replies
for example: An electric power company decides to ship 30 000 W of power at 20 000V over 2.5 \Omega transmission lines. How much power is lost over the lines.
I got the right answer by using is P=IV to get I. Then using P=I2R to get the power lost.
But if I use P=V2/R I...
I was wondering what the different power equations are used for...
P=IV, P=I2R, and P=V2/R
I was solving for power loss and I noticed that using P=I2R gave me the right answer but the other two gave me different answers
