Molarity. Molarity Molarity (M) or molar concentration is a measure of the concentration of a solute in a solution. Unit for molar concentration is mol/L.

CONCENTRATION OF SOLUTIONS Day 4 CONCENTRATION  A measurement of the amount of solute in a given amount of solvent or solution (unit of measurement.

Titration Calculations. An example of titration problem: I have a mL sample of a strong acid at an unknown concentration. After adding mL.

Molar Concentration. Measuring Concentration Molarity (M): the number of moles of solute in 1 liter solution. Example: 0.5 moles of NaCl dissolved in.

Neutralization Reaction

Leave space between each step to add more information. 1.Write a balance chemical equation between the acid and the base. Remember it’s a double replacement.

What type of reaction? HCl + NaOH  H2O + NaCl

Concentration Concentration is the amount of solute dissolved in an amount of solution. Molar concentration is called Molarity, or M. M = moles.

Acids and Bases Calculating Excess. Mixing strong acids and bases During an experiment, a student pours 25.0 mL of 1.40 mol/L nitric acid into a beaker.

a measure of the amount of solute that is dissolved in a given quantity of solvent unit of measurement is Molarity (M) which is moles/liter can be dilute.

Molarity Molarity (M) = # moles of solute/ # liters of solution Calculate the molarity of 557 mL of solution containing mol HCl. Molarity(M) = #

Solution Stoichiometry. We have already explored gravimetric stoichiometry (mass-to-mass) However, most industrial reactions take place in solution –Easier.

Percent by mass, mole fraction, molarity, and molality

Making Dilutions. Diluting a solution reduces the number of moles of solute per unit volume, but the total number of moles does not change. Higher molarity.

Solutions Molarity.

 If a VOLUME is mentioned, and the problem involves molarity DO NOT assume that 22.4L should be used. STP is only used when it says STP in the question.

Dilutions. A dilution occurs when water is added to a concentrated solution. Because only water is being added, the moles of solute is unchanged. When.

Chemists describe solutions in terms of concentration. We define the concentration of a solution as the amount of solute in a given volume of solution.

ICE Charts With Acid Base Reactions

1. 250. 0 mL of 0. 100 M H2SO4 reacts with 600. 0 mL of 0. 0500 M NaOH 1. 250.0 mL of 0.100 M H2SO4 reacts with 600.0 mL of 0.0500 M NaOH. Calculate the concentration of the excess acid or base. H2SO4 + 2 NaOH Na2SO4 + 2 HOH 0.2500 L x 0.100 mol 0.6000 L x 0.0500 mol 1 L 1 L Total Volume I 0.0250 mol 0.0300 mol 250.0 mL + 600.0 mL C 0.0150 mol 0.0300 mol E 0.0100 mol 0.0000 mol 0.0100 mol [ H2SO4 ] = = 0.0118 M 0.8500 L

The new volume = 300.0 ml + 100.0 mL = 400.0 mL 2. 300.0 mL of 0.100 M H2SO4 is mixed with 100.0 mL of 0.650 M NaOH , calculate the concentration of the excess acid or base? H2SO4 + 2NaOH 0.300 L x 0.100 mole 0.100 L x 0.650 mole L L I 0.0300 mole 0.0650 mole C 0.0300 mole 0.0600 mole E 0.0000 mole 0.0050 mole The two solutions are mixed therefore you need to add the volumes to get the molarity! The new volume = 300.0 ml + 100.0 mL = 400.0 mL [NaOH] = 0.0050 mole = 0.013M 0.400 L Note the loss of 1 sig fig! 2 sig figs!
