Surface Area and Rate of Reaction Investigation

Surface Area and Rate of Reaction Investigation

Aim- To determine how the surface area of marble chips (CaCo3) affects

the rate of reaction when placed in hydrochloric acid.

Below there’s two diagram of hydrogen ions and layer of atom and the

other diagram is the hydrogen ions being spilt up.

Equipment list- the equipment I will be using for this experiment to

see how the surface area of marble chips (caco3) affect the rate of

reaction when placed in hydrochloric acid, are 25 ml of hydrochloric

acid, 3g of marble chips, graduated cylinder, a stop clock, test tube,

250 ml beaker, delivery tube, scale, ceramic mount, and a plastic

dish.

Method- First I fill up a small container will regular tap water from

the taps of the school science table filling it up three-quarters of

the way up. After I lay a delivery tube in the middle of the container

plus straight on top the delivery tube place a ceramic mount. Now I

get a 250ml beaker and place in it 25 ml of hydrochloric acid, after

that connect both the bucket and beaker with the delivery tube. Now I

get a stop clock that is accurate for experiment. Now I carefully,

simultaneously put 3 gram of CaCo3 (marble chips) into the beaker with

HCL (Hydrochloric acid) in it and start the stop clock.

Prediction- My prediction is that the powdered marble chips (CaCo3)

will be a faster rate of reaction when it is placed in the

hydrochloric acid (HCL). The marble chips in powder form made this

happen, as they have a much larger surface area then unpowdered marble

chip. This will be showing to the hydrochloric acid faster making it a

quicker reaction. But if the marble chips are put in when it wasn’t

powder form then it would have little surface area are touching the

hydrochloric acid and as a result the reaction will take more time

then the powdered marble chips. Whilst the chemical reaction occurs

the particles of the reactants collide, but if they have a collision
