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

What volume of a concentrated HCl solution, which is 36.0% HCl by mass and has a density of 1.179 g/mL, should be used to make 4
geniusboy [140]

Answer:

5.195 ml

Explanation:

Dissociation of HCl yields;

HCl(aq)   ⇄   H⁺(aq)     +    Cl⁻(aq)

∴ [HCl] = [H⁺] = [Cl⁻]

pH = 1.9

= -log[ H⁺]

= 10^{-pH}

= 10^{-1.9}

= 0.01258 M

Moles of HCl = number of mole × volume

= 0.01258 × 4.80 L

= 0.06042 mole

Mass of HCl = number of moles of HCl  ×  Molar mass of HCl

Mass of HCl = 0.06042 mol ×  36.5 g/mol

Mass of HCl = 2.205 grams

Also, given that the density =  1.179 g/mL

Mass of HCl in the solution = 36% of the density

i.e \frac{36}{100}*1.179

= 0.4244 grams

Volume of a concentrated HCl solution needed can now be determined as;

= \frac{2.205}{0.4244}

= 5.195 ml

The chemical formula for baking soda is NaHCO. Does baking soda contain metallic or non-metallic elements? Which one is which?
Fed [463]

Answer:

Both metals and non metals.

Explanation:

The correct formula of baking soda is NaHCO₃,

An element is considered to be metal if it is able to give electron easily due to very low ionization energy.

A non metal is ready to accept electron easily due to high electron affinity.

In sodium bicarbonate :

Na: Sodium : metal

H : Hydrogen: non metal (although placed with first group, alkali metals, in the periodic table as it readily loses electron like metals)

C: Carbon: Non metal

O : Oxygen : Non metal.

So the compound contains both metals and non metals.
