What is the pH of an HCL solution if [H+]=0.03​

Chemistry

4 0

Answer:

pH = 1.5

Explanation:

The pH is always equal to -log[H+].

Simply plug it into this formula to find the pH. In order to find the concentration from the pH, you can do:

10^{-pH} = [H+]

The answer for the following problem is mentioned below.

  • <u><em>Therefore the pH of an HCl solution is 1.52.</em></u>

Explanation:

<u>pH:</u>

It is a measure of the hydrogen ion concentration,a measure of acidity or the alkalinity of a solution.    

                                           (or)

The negative logarithmic function of the hydrogen ion concentration is called the pH.

The formula for the pH is as follows:

<u>pH = -log [</u>H^{+}<u>]</u>

pH less than 7 indicates that solution is acidic

pH greater than 7 indicates that the solution is basic

Given:

hydrogen ion concentration [H^{+}] = 0.03 = 3 ×10^{-2}

To calculate:

pH of a solution

We know;

<u>pH = -log [</u>H^{+}<u>]</u>

<u>where,</u>

<u></u>H^{+} represents the hydrogen ion concentration

pH = -log [3×10^-2]

pH = 1.52

Therefore the pH of a solution is 1.52

<u><em>Therefore the pH of an HCl solution is 1.52.</em></u>

By what mechanism does cyclohexanol react when treated in sulfuric acid and what compound results?A) E 1; methoxycyclohexane B)
tensa zangetsu [6.8K]

Answer:

E 1: cyclohexene

Explanation:

This reaction is an example of the dehydration of cyclic alcohols. The reaction proceeds in the following steps;

1) The first step of the process is the protonation of the cyclohexanol by the acid. This now yields H2O^+ attached to the cyclohexane ring.

2) the water molecule, which a good leaving group now leaves yielding a carbocation. This now leaves a cyclohexane carbocation which is highly reactive.

3) A water molecule now abstracts a proton from the carbon adjacent to the carbocation leading to the formation of cyclohexene and the regeneration of the acid catalyst. This is an E1 mechanism because it proceeds via a carbocation intermediate and not a concerted transition state, hence the answer.

What is the H+ concentration for an aqueous solution with pOH = 4.01 at 25 ∘C? Express your answer to two significant figures an
EleoNora [17]

I believe pH = -log[H+]

Also, 14 = pH + pOH

Therefore pH = 14 - pOH

pH = 14 - 4.01

pH = 9.99

9.99 = -log[H+]

Solve for H+

Calculate the mass of 488 moles of calcium carbonate
san4es73 [151]

Answer: 48800g

Explanation:

Using the mathematical relation : Moles = Mass / Molar Mass

Moles = 488

Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol

Therefore

488 = mass / 100 = 48800g
