Colorful chemicals

Today's laboratary is on determining the dissociation constant for red methyl. The chemicals are so colorful after they were diluted into different concentration and acidity.

Determining pH with pH metre

The demonstrator, Mr Lau is a bit nasty. But actually he is kind but just like to make fun of us =| He did not allow us to go earlier even though we were able to complete the experiment at 11am. The lab assistant told us that we can go but this Mr Lau just refused to let us go so early. Another demonstrator, Miss Lee did nothing but just follow what ever he said.

Anyway, since all of us were busy crapping since the work is done and he could not stand with the noise, he finally let us go at 11.30am, 30 minutes earlier before the actual class t ime =)

I am going out later. I am going to buy something for Diana as a present for her convocation. But I still have no idea of what should I buy...
