Research 10: How much CO2?

Intro

The goal of this lab was to determine the quantity of grams of sodium bicarbonate (NaHCO3) needed to produce enough CO2 gas to completely load the lab and in addition how a large number of Alka-Seltzer tablets that would equal. This was made by collecting CARBON DIOXIDE gas by inverting a buret and submerging this under drinking water in order to estimate the volume of CO2 unveiled from a fraction of Alka-Seltzer tablet. The primary component of Alka-Seltzer is sodium bicarbonate, accustomed to neutralize surplus stomach acid during illness throughout the following response that builds CO2: HCO3- + H+(aq) H2CO3(aq) CO2(g) + H2O

Experimental:

An Alka-Seltzer tablet was accurately weighed and recorded utilizing a weighing boat and deductive balance. A fragmented part between 0. 2100g and 0. 2800g was likewise weighed and recorded. 500mL of normal water was put in a 600mL beaker. 80mL of drinking water was then simply mixed with 20mL of 6M HCl in a 150mL beaker to create 1 . 2M HCl. A 1. 5g piece of Alka-Seltzer tablet was then put into the HCl solution. After complete advancement of CARBON DIOXIDE, gravity purification was used to catch all of the starch created from the reaction. The buret was filled with the filtrated answer and the goblet tube end of a rubberized tube was inserted about 2 ins into the mouth of the buret. Although keeping a finger within the buret oral cavity, the entire buret was quickly inverted and the tubing and mouth totally submerged into the water inside the 600mL beaker. The buret was then simply clamped in to place when double checking the buret mouth was underneath the water level plus the rubber tubes was not pinched. The stopcock was then simply opened incredibly slowly until the water level in the buret lowered close to the 50. 00mL indicate. This level was after that recorded.

25mL of the prepared HCl option was included with a 125mL Erlenmeyer flask, along with a 0. 5-1. 0g piece of Alka-Seltzer tablet. Following complete development of LASER, the neck of the flask and rubber stopper were completely dried out. The tablet fragment...
