Answer:

Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.

Calculate the concentration of H3O+ in a solution that contains 5.5 × 10-5 M OH- at 25°C. Identify the solution as acidic, basic
k0ka [10]

Explanation:

To calculate [H3O+] in the solution we must first find the pH from the [ OH-]

That's

pH + pOH = 14

pH = 14 - pOH

To calculate the pOH we use the formula

pOH = - log [OH-]

And [OH-] = 5.5 × 10^-5 M

So we have

pOH = - log 5.5 × 10^ - 5

pOH = 4.26

Since we've found the pOH we can now find the pH

That's

pH = 14 - 4.26

pH = 9.74

Now we can find the concentration of H3O+ in the solution using the formula

pH = - log H3O+

9.74 = - log H3O+

Find the antilog of both sides

<h2> H3O+ = 1.8 × 10^ - 10 M</h2>

The solution is basic since it's pH lies in the basic region.

Hope this helps you

2.4  ×    10⁻² is the pH of a solution

What is the short definition of pH?

  • The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

Equation representing the i onization of Na₃PO₄ is as fallow

              Na₃PO₄          →                 PO₄³⁻    +  3Na⁺

Concentration of Na₃PO₄ = \frac{26.9 * \frac{1 mol}{164 g} }{1 L} = 0.164 M

Since 1 mol of Na₃PO₄ forms 1 mol of  PO₄³⁻  [  PO₄³⁻  ] = [ Na₃PO₄ ] = 0.164 M

Equation representing the  i onization of HPO²⁻₄ is as fallow

 HPO²⁻₄          →         PO₄³⁻  +    H⁺

Acidionization constant Ka₃ of   HPO²⁻₄  = 4. 17 ×  10⁻¹³

Baseionization constant  Kb₃ of  PO₄³⁻ = Ka₃/ Kb₃

                              = 1 .0  ×  10⁻¹⁴/  4. 17 ×  10⁻¹³  = 2.4  ×    10⁻²

What contribution did Robert Boyle make towards the field of chemistry
GREYUIT [131]

Answer:

Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, The Sceptical Chymist is seen as a cornerstone book in the field of chemistry.

Solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate
antiseptic1488 [7]

<u>Answer:</u> The chemical equation for the given reaction is given below.

<u>Explanation:</u>

When solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate, the chemical equation follows:

CaO(s)+SO_3(g)\rightarrow CaSO_4(s)

This is the reaction when a metal oxide reacts with non-metal oxide to produce a salt.

By Stoichiometry of the reaction:

1 mole of solid calcium oxide reacts with 1 mole of sulfur trioxide gas to produce 1 mole of solid calcium sulfate.
