Acid Rain Thingy,

Observing the Effects Of Acid Rain,

Acid rain makes Chemical weathering happen more quickly. Buildings and Statues made from Rock are Damaged as a result. This is worse when the rock is Limestone Rather then granite. Oamaru stone is New Zealand most important building stone and is a very pure limestone. It is soft enough to be easily sawn and worked. unfortunately, These propities make it very susceptible to the effects of acid rain.

Aim, To see the effect of limestone From acid rain,

Equipment,

• Petre Dish,
• Apple,
• Calcium carbonate,
• Leaf,
• Flower,
• Litmus paper (blue)
• Universal indicator,
• weigh boat,
• Hydrochloride acid,
• Bromothynol,

Hazards that were in the Experiment,

1. Corrosive,
2. non-Eco safety,
3. eye protection,

Method:

1. Make sure you have all of the equipment.
2. Evenly Spread out the Leave, Flower, Litmas paper, Universal indecator

Acid+base

Aim-To make Green indicator.

Hypothesis- I predict I could not make a rainbow,

Method-Adding a drop of either Sodium hydroxide to a testube and/or Hydrochloride acid,

Results- all i got was a Red, Green, Lime, Light blue and a Dark Oceanic blue.

Discussion- We added more Hydrochloride acid and Sodium Hydroxide to it to change the colors,

Conclusion, No it did not work as well as i planned we had more of a rainbow then what i Expected.
