Was away for this practicle information supplied by Nickeel Naidu
In this practicle we had to observe the Displacement reaction. We added a strip of Zinc with copper solution nad had to observe the reaction.
The zinc a a paermanent colour change of black which was a great way of showing displacement
DISPLACEMENT RESULTS
Group Work
The group is getting along better however i have been away on holidays longer than everyone else so I have fallen behind alot so I need to catch up. I have caught up on the practicles last time i fell behind and now i only missed one. I should catch up quick
We have planned for [...]
NEUTRALISATION
In this experiment we had a look at the pH scale. We had to mix Hydrochloric acid with a univeral indicator than a _______ with a univeral indicator. We then mixed Hydrochloric acid and _______ and added a univeral indicator
With the hydrochloric acid it went to pH 10 and with the base it went to [...]
PRECIPITATION RESULTS
Precipitation is the forming of one ore more solids after combining 2 or more liquids. In this experiment we had mixed 5 drops of silver nitrate with 3 drops of sodium chloride
The hypothesis was that a solid would be formed and it was correct. A solid was formed about two minutes after the liquids were [...]
COMMON INDICATORS RESULTS
The point of this experiment was to look at the various types of indicators in acidic and basic solutions. We had a base Sodium Hydroxide and and acid which was Hydrochloric and a neutral which was distilled water.
Bromothyl Blue, Red litmus, Universal Indicator, methyl orange, methyl red phendphtlalein were the indicators.
Bromothyl Blue turned neutral Yellow the [...]
METALS AND ACIDS RESULTS
This experiment shows who metals react with acids. In this experiment Hydrochloric Sulphric and Acidic acid will be mixed with each Aluminium, magnesium, zinc and iron
All metals except for iron had gas being released when mixed with each of the acids and exspecially magnesium which had a high levels of bubbling.
A match test was used [...]
GROUP WORK
My group is going along well. We are all trying to get the practicle write ups done and then type up. Maybe we can get more done because we may have been slacking a little bit
I have been away for a few lessons and have missed some practicles and I have caught up on them
COMBUSTION RESULTS
For this experiment I was away and therefore all information was provide by Stephen Noone
This experiment was supposed to show how substances combust when come in contact with fire and oxygen. Magnesium was put over an open fire and let to combust.
The magnesium combusted very well when it came in contact with fire and oxygen [...]
DECOMPOSITION
For this experiment I was away and therefore all information was provide by Stephen Noone
In the decompostion experiment it was to be investigated how a substance breaks down. We were to Have limewater in one test tube and copper carbonate in another test tube and have them connected by a rubber tube. The copper nitrate was [...]
CORROSION RESULTS
For the corrosion experiment we investigated what happenes to a nail when its left in silica gel, air, water and oil over 2 weeks
For oil nail it rusted and the nexture changed to a bit slimy. In Water it rusted very heavly and was very thin twowards the midle.The nail had very little change and [...]
