How do I find the concentration of a solution?

Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.

What happens if you over titrate a solution?

If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.

Can I titrate a solution of unknown concentration with another solution of unknown concentration?

Can I titrate a solution of unknown concentration with another solution of unknown concentration and still get a wond meaningful answer? Explain your answer in a few sentences. No! You Must Knows at least one concentration to determine moles so that stoichiometry can be done.

How do you find the molarity of a solution using titration?

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

When you add NaOH to a solution the pH of the solution should?

The hydroxide ions from dissolved sodium hydroxide perturb this balance; as the additional hydroxides accept protons from hydronium ions, they decrease the hydrogen ion concentration, thereby increasing the pH. Adding more sodium hydroxide will increase the pH of the water or make it more basic.

How do you make sodium hydroxide solution?

To make 1 M NaOH solution, you have to dissolve 40.00 g of sodium hydroxide pellets in 250 mL distilled water and then make up the solution to 1 liter. Weigh 19.95 gm of NaOH pellets & dissolve them in half liter(500ml) of distilled water water, what you will be having now is 1M NaOH solution.

What is acid base titration in chemistry?

Acid-Base Titrations Titration:reaction of an acid with a base (neutralization) Specifically, the addition of a solution of accurately known concentration (e.g.acid) to a solution of unknown concentration (e.g.base) until the reaction is complete.

How do you calculate acid base equilibria?

Acid-base equilibria and calculations • 1 Proton donor-acceptor equilibria 1 Proton donor-acceptor equilibria In order to describe acid-base equilibria in the most general way, we will often represent an acid by the formula HA and its conjugate base as A .

What is acid-base indicator?

Acid-base indicator: is a weak organic acid or base for which the ionized and un- ionized forms (i.e. weak acid and conjugate base, or weak base and conjugate acid) are different colors The pH range over which the indicator changes color depends on the value of its K

What is the concentration of unreacted ethanoic acid in NaOH?

= 12 mmol – 3.0 mmol Unreacted ethanoic acid = 9.0 mmol Since 10.00 mL of NaOH(aq) was added to 20.00 mL of ethanoic acid solution, the total volume is now 30.00 mL. Solution: The concentration of unreacted ethanoic acid, [HC
