SKILLL: Planning and Designing

PROBLEM: Grandma suffers from acid reflux. She generally uses Andrews salts although her pharmacologist recommends tums.

HYPOTHESIS: Tums is more effective for heartburns that Andrews salts when utilized.

AIM: To look for the effectiveness of Calcium Carbonate and Sodium Carbonate when used to deal with heartburns.

EQUIPMENT: Measuring Tube, Beakers, Spatula, Conical Flask, Measuring Range, Funnel, Water down HCL, Calcium supplements Carbonate (Present in Tums), Sodium Carbonate (Present in Andrews Salts), Petri Dish, Rubber Arreter, Gas Syringe METHOD: 1 ) Wash most apparatus.

2 . Assess and transfer 5g Calcium supplement Carbonate to Petri Dish. 3. Evaluate and transfer 25cm3 of HCL to Beaker. 5. Place acidity into conical flask and Calcium Carbonate and cover Immediately with rubber arreter to prevent gas from escaping. Apparatus should certainly adopt the trend below:

Diagram showing apparatus set up.

five. Allow gas to fully develop from flask. Measure the gas collected in syringe.

6th. Repeat steps 2-5 using the Sodium Carbonate. Tabulate results in table beneath.

COMPOUNDS

EFFECT TIME/MINS

SUM OF GAS COLLECTED

Calcium Carbonate

Salt Carbonate

VARIABLES: 1 . Control: Masses of Ca(Co3)2 and Na2Co3, Vol. of HCL and Conc. Of HCL.

2 . Manipulated: Carbonates

3. Answering: Gas Progression

EXPECTED RESULTS: It is predicted that Calcium Carbonate could have a more quickly rate of reactivity when being responded with Hydrochloric acid and still have a larger measure of gas collected than the Sodium Carbonate. The gas likely to evolve from the conical flask to the gas syringe in both reactions with the substances is Carbon. Equation...
