Tollens\' reagent, [Ag(NH3)2] , is used to test for the presence of aldehydes. The reaction results in reduction of the silver i
on to form a mirror of silver metal. Concurrently, the aldehyde is oxidized. Draw the structure of the organic product resulting from treatment of 3-methylbutanal with Tollens\' reagent, followed by treatment with acid.

Answer:
On the attached picture
Explanation:
Hello,
As long as the addition of the Tollen's reagent turn out in to the oxidation of the aldehyde, the formed product will be its corresponding carboxylic acid, this is 3-methylbutanoic acid whose structure is shown on the attached picture in the form of the oxidation reaction.
Best regards.

Answer:
0,07448M of phosphate buffer
Explanation:
sodium monohydrogenphosphate (Na₂HP) and sodium dihydrogenphosphate (NaH₂P) react with HCl thus:
Na₂HP + HCl ⇄ NaH₂P + NaCl <em>(1)</em>
NaH₂P + HCl ⇄ H₃P + NaCl <em>(2)</em>
The first endpoint is due the reaction (1), When all phosphate buffer is as NaH₂P form, begins the second reaction. That means that the second endpoint is due the total concentration of phosphate that is obtained thus:
0,01862L of HCl×= 1,862x10⁻³moles of HCl ≡ moles of phosphate buffer.
The concentration is:
= <em>0,07448M of phosphate buffer</em>
<em></em>
