Questions about the Esters poster

What’s on the Esters poster?

Esterification against Hydrolysis, side by side. Esterification: Carboxylic acid + alcohol; Esterification: Concentrated H₂SO₄ catalyst; Esterification: Reversible; equilibrium; Esterification: Remove water to drive it forward; Esterification: Named acid-part last: ethyl ethanoate; Hydrolysis: Acid hydrolysis: reversible, gives acid + alcohol; Hydrolysis: Alkaline hydrolysis: irreversible, gives salt + alcohol; Hydrolysis: Alkaline goes to completion; Hydrolysis: Saponification makes soap; Alkaline hydrolysis is irreversible because the carboxylate salt formed cannot react…. Naming: the alcohol part comes first, then the acid part as -oate. Ethanol plus ethanoic acid gives ethyl ethanoate.

Who is the Esters poster for?

Esters belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning organic can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Esters poster?

Acid plus alcohol, with an acid catalyst. The reaction is reversible. A wall chart earns its place by being glanceable from where the work is happening, so Esters belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Esters?

Carboxylic Acids, Alcohols and Alkanes sit alongside Esters in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Carboxylic AcidsAlcoholsAlkanes

Is the Esters poster free to download and print?

Yes. Esters downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Esters poster print at?

Esters is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Esters loses nothing.Printing guide
