In this high-yield DAT General Chemistry problem, Dr. Jim Romano explains how to determine the pH of a complex ion and how coordination chemistry concepts apply to acids and bases on the DAT. Students often underestimate this topic, but equilibrium and complex ion behavior are frequently...

In this short video, Prof. Blois breaks down one of the most commonly tested DAT Quantitative Reasoning topics: combinations vs permutations. Many students lose points not because the math is difficult, but because they confuse when order matters and when it does not. If you are beginning...

We would like to congratulate one of our students, Mr. E, on his acceptance to the Touro College of Dental Medicine — Class of 2030. Dental school admission is the culmination of years of academic effort, disciplined preparation, and perseverance. We are proud to have supported Mr. E...

Colligative properties are a classic high-yield topic on the DAT General Chemistry section. Understanding how particle number affects boiling point elevation, freezing point depression, and osmotic pressure is essential for solving many exam questions efficiently. In this video, Dr. Jim Romano...

What effect will adding additional O₂ (g) have on the following equilibrium system once equilibrium is reestablished? 2 CO₂ (g) ⇌ 2 CO (g) + O₂ (g)  ΔH° = −514 kJ a) The concentration of CO (g) will increase b) The concentration of CO₂ (g) will decrease c) The equilibrium constant for the...

Proteins are a major component of the Biology section on the DAT. In this lesson, Dr. Jim Romano reviews high-yield protein concepts including structure, function, enzymes, and amino acid properties that students are expected to understand for the exam. This material reflects over 35 years of...

Here is a classic combined work rate problem similar to what you may encounter on the Quantitative Reasoning section of the DAT. Three printers are typing a full report. • Printer A types 1/2 of the report in 2 hours • Printer B types 1 full report in 2 hours • Printer C types 1/4 of the...

Dr. Jim Romano discusses key General Chemistry applications that frequently appear on the DAT. Understanding how core principles translate into real exam questions is essential for strong performance in the General Chemistry section. Watch the video here: If you’re preparing for the DAT or...

How would you calculate Kb for the formate ion, given that the Ka for formic acid is 1.8 × 10⁻⁴ ? a. Kb = Ka × Kw b. Kb = Kw + Ka c. Kb = Kw / Ka d. Kb = Kw − Ka e. Kb = Ka / Kw Pause before scrolling if you want to simulate test conditions. Answer: C KaKb = Kw For a conjugate acid–base...
