QUESTION POSTED AT 28/02/2020 - 02:42 PM

Suppose 13.00 mL of 0.100 M barium hydroxide is required to neutralize 17.00 ml of nitric acid with an unknown concentration. What is the concentration of the nitric acid. Express your answer in mol/L

The concentration of {\text{Ba}}{\left( {{\text{OH}}} \right)_2}solution is \boxed{{\text{0}}{\text{.076 M}}}

Further Explanation:

The concentration is the proportion of substance in the mixture. The most commonly used concentration terms are as follows:

1. Molarity (M)

2. Molality (m)

3. Mole fraction (X)

4. Parts per million (ppm)

5. Mass percent ((w/w) %)

6. Volume percent ((v/v) %)

Molarity is a concentration term that is defined as the number of moles of solute dissolved in one litre of the solution. It is denoted by M and its unit is mol/L.

The molarity equation is given by the following expression:

{{\text{M}}_{\text{1}}}{{\text{V}}_{\text{1}}} = {{\text{M}}_{\text{2}}}{{\text{V}}_{\text{2}}}


{{\text{M}}_{\text{1}}} is the molarity of the first solution.

{{\text{V}}_{\text{1}}} is the volume of the first solution.

{{\text{M}}_{\text{2}}} is the molarity of the second solution.

{{\text{V}}_{_{\text{2}}}} is the volume of the second solution.

In the concerned question, {\text{Ba}}{\left( {{\text{OH}}} \right)_2}is neutralized by {\text{HN}}{{\text{O}}_{\text{3}}}. So molarity equation becomes,

{{\text{M}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}}{{\text{V}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}} = {{\text{M}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}}{{\text{V}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}}                           …… (1)


{{\text{M}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}} is the molarity of {\text{Ba}}{\left( {{\text{OH}}} \right)_2} solution.

{{\text{V}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}}is the volume of {\text{Ba}}{\left( {{\text{OH}}} \right)_2}solution.

{{\text{M}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}} is the molarity of {\text{HN}}{{\text{O}}_{\text{3}}}solution.

{{\text{V}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}} is the volume of {\text{HN}}{{\text{O}}_{\text{3}}}solution.

Rearrange equation (1) to calculate {{\text{M}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}}.

{{\text{M}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}} = \frac{{{{\text{M}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}}{{\text{V}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}}}}{{{{\text{V}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}}}}                                       …… (2)

The value of {{\text{V}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}} is 13 mL.

The value of {{\text{M}}_{{\text{Ba}}{{\left( {{\text{OH}}} \right)}_2}}} is 0.100 M.

The value of {{\text{V}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}} is 17 mL.

Substitute these values in equation (2).

\begin{aligned}{{\text{M}}_{{\text{HN}}{{\text{O}}_{\text{3}}}}}&=\frac{{\left( {{\text{0}}{\text{.100 M}}} \right)\left( {{\text{13 mL}}} \right)}}{{\left( {{\text{17 mL}}}\right)}}\\&=0.{\text{07647 M}}\\&\approx {\text{0}}{\text{.076 M}}\\\end{aligned}

Hence the concentration of barium hydroxide solution is 0.076 M.

D.The biosphere gets resources from Earth's crust, hydrosphere and atmophere

Answer: c. Light and heat from the sun don't affect the biosphere.


The biosphere is the sphere where living beings such as plants, animals, microbes, humans and others survive, reproduce and lead their life cycle.  

The atmosphere is a sphere of the earth. It consists of collection of different gas called as air. It protects the biosphere by absorbing the incident harmful radiations along with heat coming from the sun.

  • The correct answer is C.
  • Basic


  • The pH scale is 0-14. The values from 0-6 show acidic properties while at 7 pH, it act as neutral while from 8-14 shows basic properties.

pH less than 7

pH less than 7 describe the acidic solution

pH equal to 7

pH equal to 7 describe that solution is neither acidic nor basic. It is neutral


Basic solution describe the alkaline solution, so it is correct one. The alkaline solution has same range as basic solution


Acids describe the acidic solution , not a alkaline solution

5. In this lab, you continued to add Reagent D to each solution until it turned blue. The purpose was to remove the oxygen to measure how much was left. The more drops you had to add to acquire the blue color, the more oxygen was present in the tube. In which phase(s) did the solution turn blue before you added Reagent D? What do you think that means? NO FALSE ANSWERS

A solution is turning blue means, it is turning it's behavior to Basic from Acidic. Reagent D must be a Basic component so it is increasing the pH of the solution. As reaction does not depend on the phase of the component, it could be anything i.e., Solid, Liquid or gas.

Hope this helps!

Which of the following would increase the conductivity of a connecting wire? (More than one answer). A) increase the diameter B) increase the length of the wire C) decrease the temperature o the wire D) switch from steel wire to gold wire

All but length I suppose. Diameter would definitely increase the conductivity of a wire, that's why jumper cables are so big, to conduct very large amounts of electricity. Also decreasing temperature allows for a faster flow of electrons causing better conductivity. Finally, Gold is very, very conductive and would be used in wires everywhere if it weren't so expensive(that's why copper is used a lot instead) also gold is quite delicatewouldn't want to bend it back and forth a lot like most wires but simply put, yes. Gold would also very much up the conductivity.

The forces between water molecules are stronger than the forces between ethanol molecules. Which liquid would probably be most difficult for an insect to walk on? Explain your answer.

An insect would have an easier time walking on the surface of water than on the surface of ethanol. Water's stronger intermolecular forces lead to higher surface tension. Higher surface tension allows water to support the insect. I hope this helps.
