Biology (Anatomy & Physiology 1-2) || Chemistry (General & Organic)
I know how busy pre-meds/nursing majors are, so I hope my page helps make school a little less stressful!
* All lab reports I have posted include grades received/any helpful notes. Work is shown, step by step, making it is easy to follow!
* Please feel free to let me know if there are any updates I need to make for future students =)

CHEM 223. Lab Report 7 - Nucleophilic Substitution & IR Spectroscopy. Hunter College.
Stock solvent-nucleophile medium (SNM) was prepared (NH4B R/H2S O4) in order to observe reactions that occurs after the addition of a primary (1°) alcohol (1-butanol) and a tertiary (3°) alcohol (2-Methyl-2-butanol), respectively. Infrared (IR) Spectroscopy was used and recorded. Lab was done online, during COVID 19. All IR Spectra are still included, which are all correctly drawn =)

CHEM 223 - Lab Report 3, Simple & Fractional Distillation
A mixture of methanol-water was distilled (Simple distillation, fractional distillation) and temperature at which the sample boiled was recorded. The results of both distillations were compared and graphed (mL of distillate vs Temperature). Done in lab, before COVID 19. For Hunter College's CHEM 223. Includes all work for post lab questions.

CHEM 223 Lab Report 2 - Recrystallization. Hunter College.
An unknown solid was purified, through recrystallization, in order to determine its identity. The mixed melting point technique was employed to confirm the identity of the pure solid, using given reference samples. All calculations, graphs, tables, and post lab questions are included. Experiment done in lab, before COVID-19.

CHEM 223 Lab Report 1 - Melting Point. Hunter College.
The melting point of 2 known compounds (trans-cinnamic acid & urea) were measured in order to observe changes that occur once they are mixed in a 1:1 ratio. Using similar methods, the melting point of an unknown compound was determined. To confirm the identity of the unknown solid, a 1:1 sample of the unknown and a reference sample. Experiment done in lab, before COVID-19.

Lab Report 14. CHEM 106. Acids and Bases are pHun. Hunter College.
****NOTE: 2 pre-made indicators were contaminated so some colors came out WRONG for the entire class! =( I label them as "error" so you guys know which ones. I mention the CORRECT colors in my discussion. Lab Report 14. CHEM 106. Acids and Bases are pHun: Acids, bases, salts, and buffers. CUNY - Hunter College. Complete lab with step by step calculations for all the Ka Values vs. Kb Values , Calculated pH, and Relative Strength for the Species found in table 2. Titration Figures, images of o...
