The pH value of the solution is mathematically given as

pH=2.35

<h3>What pH value of the solution?</h3>

Question Parameters:

pH during the titration of 20.00 mL of 0.1000 M dimethylamine,

with 0.1000 M HCl(aq) after 21.23 mL of the acid

Generally, the equation for the Chemical Reaction is mathematically given as

(CH3)2NH(aq), +Hcl ---> <---- (CH3)2NH2Cl(aq)

Therefore

$HCl=\frac{0.186mol}{41.86}$

HCL=0.00444M

WHere

HClaq--->H+(aq)+Cl-(aq)

Hence

H+=0.00444M

pH= -log{H+}

pH=log(0.00444)

pH=2.35
