0:02going to use on principles fun
0:06the koran concentration in tap water
0:10now the tap water reason today Islami
0:14tap water slowing British Columbia
0:17can we placed
0:21in to appear at solution up
0:250.1 molar
0:29silver nitrate today we're using it here
0:340.1 bowler psyllium
0:38crewmen any to CR all
0:41for the principle behind the slap
0:46this is false the silver nitrate
0:50is added to a solution up catwalk
0:53the summer
1:00preferentially Ponce or combines
1:04that is forms in person take we're
1:08see all minus to form a precipitate out
1:12AG yup what happens is
1:16where although chlorine ions are used up
1:21the summer all on the call me
1:25producing a reddish-brown solution so what we try to do is
1:33we country very slowly
1:38until we see a reddish-brown solution now indicate to us
1:42and point using
1:46the ball you a silver nitrate
1:49the concentration its overnight rate
1:53and the volume in this case
1:57100 mils on water
2:00we can find the concentration I'll the crys-
2:04I remember we're using the net
2:08I don't question in this case
2:12AG see also our is in equilibrium where
2:17AG lost files and CEO minus
2:20what we're gonna do
2:23his first are approximately
2:27to Mills
2:31I'm indicated
2:44knows the old
2:48well you know is what I trade
2:51now it's very important before we begin
2:56to record the initial volume on you're at
2:59now the initial reading on the pier at yes
3:030 point
3:078 Mills 0
3:11point the Mills its also
3:15important good habit to place a white piece of paper
3:20attorney not allow us to see the color change
3:25more clear let's just get he's now
3:35soulless paper attorney not just allow us to see
3:39change color was knowing what it was we were slowly
3:44at a silver
3:49nitrate just turn the opening
3:54here really slowly you know is initially
3:57we have a fresh round solution what we gotta do
4:01stir knows disappears well you know I was
4:06at dropwise until the reddish brown color
4:11doesn't disappear
4:18know the date today July for
4:22headed out candid knows
4:27lawyer
4:32know what I've done is upset about also at very slowly
4:36lowers still have a solution
4:40it's snowing
4:47no do is know that drop has been
4:51knows the solution turn a slight
4:56branch our it's just cool like
5:00here North like
