What is the hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4.
Maksim231197 [3]

The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7.

pH= -log[H+] - (i)

10^-3=H2So4

H+= 2×10-3

here ,

h2so4 ——— 2[H+] + so4^2-

thus [H+]= 2*10^(-3) because hydrogen ion has two moles

pH= -log[H+]

pH= -log(2×10^-3)

pH= 3-log2

pH= 3-log2pH= 2.7

The pH is 2.7

<h3>What is pH?</h3>

PH is the degree of alkalinity and acidicity in a solution.

Therefore, The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7

Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.

<h3>What is Flame Test ?</h3>

A Flame test is used to identify the metal and metalloid ion in the sample. Flame test is a qualitative test. Not every metal ion emit color when it is heated in the gas burner.

<h3>What is the Purpose of Flame test ?</h3>

The purpose of flame test is used to find the identities of ions in two solutions of unknown composition by comparing the colors they produce.

<h3>What are the material used ?</h3>
  • Bunsen Burner
  • Matches
  • Gloves
  • Weighing dishes
  • Beakers

Thus from the above conclusion we can say that Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.
