How much NaOH is in a drain cleaner?

Liquid formulations of corrosive alkaline drain cleaners can contain sodium hypochlorite (bleach) and lye (sodium hydroxide or potassium hydroxide) in concentrations up to 50 percent.

What is the molarity of sodium hydroxide in the full strength drain cleaner?

Commercial drain cleaner for sinks and toilets often contain sodium hydroxide as a corrosive agent to clear the clog. A particular brand contains 6.5% m/v sodium hydroxide, and recommends using 450 mL to clear a drain.

What is the molar mass of sodium hydroxide NaOH that is used to unclog drains?

The molar mass of the compound NaOH is 40 g/mol.

What is the molarity of NaOH?

Dilutions to Make a 1 Molar Solution

How do you drain with NaOH?

Add 3 cups of sodium hydroxide to the water and stir with a plastic or wooden spoon. The mixture will begin to fizz and heat up in an exothermic reaction with the water. Pour your aqueous solution of sodium hydroxide into your sink or drain and wait for 30 minutes before rinsing with boiling water.

Can sodium hydroxide be used as drain cleaner?

Sodium hydroxide is a base, and sulfuric acid is an acid; they neutralize each other when you combine them. Drano is a popular product, so caustic soda is definitely effective for clearing drains.

How do you find the molarity of standardized NaOH?

The molarity of the NaOH solution is found by dividing the moles of NaOH by the liters of NaOH solution required to reach the endpoint of the titration. The mass percent of KHP in an unknown mixture is found by titrating a weighed sample of the mixture with the NaOH solution whose molarity was found in Part A.

How do you find the molarity of NaOH?

The molarity of the NaOH solution is found by dividing the moles of NaOH by the liters of NaOH solution required to reach the endpoint of the titration.

How do you calculate the molarity of NaOH?

The average molarity of NaOH titrated can be solved by getting the sum of molarity divided by the number of trials. The average molarity of NaOH titrated is 0.1325 M.

How do you dissolve solidified sodium hydroxide?

Hold the plunger at an angle over the drain opening to allow it to fill with water, then fit it around the drain and pump vigorously. If water begins to flow, even by a small amount, you’re making progress, so keep pumping to help the clog dissolve and move along.

How big is the molarity of NaOH solution?

For example, if there are 50 moles of NaOH in 500 liters of solution, it is a 0.1 molar NaOH solution.

How to prepare a sodium hydroxide or NaOH solution?

Follow these lab safety guidelines: 1 Don’t touch sodium hydroxide! 2 Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. 3 Be sure to use borosilicate glass (e.g., Pyrex) and consider immersing the container in a bucket of ice to keep the heat down.

How to calculate the molarity of H 2SO4?

An aqueous solution of H 2SO4 (molecular weight=98) contains 10.78 g of acid per dm3 of solution. Density of solution is 1.123 g / ml. What is the molarity, molality, normality and mole fraction of the solution? Can you solve this? The concentration of the Zn2+ ions in blood serum is 1.2 ppm.

What is the concentration of N O− 3?

What concentration of N O− 3 results when 697 mL of 0.515 M N aN O3 is mixed with 635 mL of 0.785 M C a(N O3)2? What concentration of N O3 – results when 697 mL of .515 M N aN O3 is mixed with 635 mL of .785 M C a(N O3)2?
