Hello! We're back again!
So for this week, the year 1s got a chance to carry out standardisation of  HCl against Sodium Carbonate which is a primary standard!
Here's the picture of HCl which was contained inside the volumetric flask~
We carried out titration against the sodium carbonate primary standard in order to find out the exact concentration of the HCl.

We added in 2 drops of methyl orange indicator to the primary standard before we begin titrating. So this was how it looks like before the start of titration~
During, the titration process, we titrated the solution of sodium carbonate in yellow with the HCl from the burette.

At the end point, a nice orange solution was observed!
We also had to be extra careful not to over-titrate the solution!:)
Aside from the lab sessions, the year 1s are also busy gearing up for the upcoming MSTs:)

Till we meet again next week!
