(b) What is the pKa of the dimethylammonium ion, (CH₃)₂NH₂⁺ ?
g100num [7]

The pKa of the dimethylammonium ion, (CH₃)₂NH₂⁺ is 10.7.

<h3>What do we know about  dimethylammonium ion?</h3>

The conjugate acid of dimethylamine, dimethylaminium is an organic cation and a significant species at pH 7.3. It is a secondary aliphatic ammonium ion and an organic cation. It is a dimethylamine conjugate acid.

<h3>What do we understand by pKa?</h3>

In layman's terms, pKa is a measurement of an acid's strength. A strong acid will have a pKa value that is lower than 0. To be more specific, pKa is the Ka value's negative log base ten value (acid dissociation constant). How tightly a proton is retained by a Bronsted acid is how the strength of an acid is measured. The strength of the acid and its capacity to donate protons increase with decreasing pKa values.

A rigid cylinder with a movable piston contains a sample of helium gas. The temperature of the gas is held
Varvara68 [4.7K]
<span>Assuming ideal gas, we can label this system to follow the Boyle's Law. This Law can be applied to systems held at constant temperature. The formula used is: PV=k, where k is a constant. From the formula, P and V are inversely proprotional. So, if you graph P vs V, the graph would start from the top, then curves down towards the right. </span>
