Prerequisites: CHEM 1311 & CHEM 1111; Co-requisite: CHEM-1312

1) “Chemical Principles in the Laboratory, CHEM 1112 Edition”, Slowinski et al. (Purple Cover)

2)  Scientific Calculator 

3)  ANSI-approved safety glasses or goggles stamped with Z87

Preparation before lab: 

1. Bring ANSI-approved safety glasses or goggles stamped with Z87.  ACC does not provide safety glasses or goggles for the lab. 
2. Read and understand the experiment being performed that week. 

Students that do not have a printed copy of the lab will be asked to leave.

3. Complete Pre-Lab Assignments.  

        4. Prepare for weekly quiz given at the beginning of lab

This course is the laboratory to accompany CHEM 1312 lecture.  Stresses the quantitative aspects of kinetics, chemical equilibria, acid-base theories, coordination complexes, thermodynamics, and electrochemistry.

Students will be able to perform the following skills: 

Read NFPA, HMIS labels and understand the hazard of chemicals used 

Transfer sample to balance for weighing and tare the balance 

Measure temperature with a thermometer 

Correctly read a meniscus and accurately measure a liquid volume 

Light and adjust Bunsen burners 

Correctly use a hot plate 

Observe and interpret chemical reactions: color change, temperature change, precipitate formation, and gas evolution 

Perform a gravity and vacuum filtration to separate liquids from solids 

Use capillary tubes to transfer liquid samples used in paper chromatography 

Use a buret to perform a standard titration and observe color change to define the end point of the titration 

Use centrifuge and decanting techniques to separate solids from liquids 

Use a coffee cup calorimeter to measure heat flow 

Measure volume of a liquid using a graduated pipet 

Use a Vortex mixer for mixing solutions 

Use a spectrophotometer to measure absorbance of a solution 

Calibrate a pH meter with buffers and measure pH with the meter 

Use Mel-Temp to determine melting points 

Set up a voltaic cell and use a voltmeter to measure voltage 

Perform neutralization reactions on collected reaction mixtures for safe disposal 

Graph experimental results and calculate slope of a line from raw data

Chem 1112 • Chemistry 2 Lab Schedule • HYS • 16 week • Spring 2020

* MLK Day is Monday, January 20 (no class), therefore the Monday section will cover
all syllabus, orientation, and lab safety information on Monday, January 27.

Attendance/Class Participation Regular and punctual class and laboratory attendance is expected of all students. If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class.

Withdrawal Policy It is the responsibility of each student to ensure that his or her name is removed from the roll should he or she decides to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or she feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records. Students who enroll for the third or subsequent time in a course taken since Fall, 2002, may be charged a higher tuition rate, for that course. State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.  The last day to drop the course is Monday, November 25 2019.

Incompletes An instructor may award a grade of “I” (Incomplete) if a student was unable to complete all of the objectives for the passing grade in a course due to medical/emergency reasons.  Students must have successfully completed at least 60% of the course materials to get an incomplete. An incomplete grade cannot be carried beyond the established date in the following semester. The completion date is determined by the instructor but may not be later than the final deadline for withdrawal in the subsequent semester.
