How do you find the molarity of NaOH in titration with H2SO4?
Step 1: List the known values and plan the problem. First determine the moles of NaOH in the reaction. From the mole ratio, calculate the moles of H2SO4 that reacted. Finally, divide the moles of H2SO4 by its volume to get the molarity.
How do you find the molarity of NaOH in a titration?
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 many moles of H2SO4 react with NaOH?
1 Expert Answer. Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water. If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water.
How do you calculate molarity from titration?
Divide the number of moles of analyte present by the original volume of the analyte. For example, if the original volume of the analyte was 500 mL, divide by 1000 mL per L to obtain 0.5 L. Divide 0.01 moles of analyte by 0.5 L to obtain 0.02 moles per liter. This is the concentration or molarity.

| Sodium Hydroxide (NaOH) | 39.997 | 19.4 |
| Potassium Hydroxide (KOH) | 56.105 | 11.7 |
What is molarity of NaOH solution?
Number of moles of NaOH=given mass of NaOHmolar mass=10−340. Step 2: Molarity=number of moles of solutevolume of solution in mL×1000. Molarity=10−340×1000250=10−4 M. Hence, option (C) is correct.
What is the reaction between H2SO4 and NaOH?
A reaction between sulfuric acid and sodium hydroxide is of an acid-base type, or is also known as a neutralization reaction. In this process, both compounds undergo a reaction to neutralize the acid and base properties. The products of this process are salt and water.
How much NaOH does it take to neutralize H2SO4?
to convert from mol of H2SO4 to mol of NaOH. And this would be how many grams? to convert from g NaOH to mol NaOH. = 1.48 g NaOH are needed to neutralize the acid.
What’s the molarity of NaOH?
How do you find molarity from neutralization?
Solving an Acid-Base Neutralization Problem
- Step 1: Calculate the number of moles of OH-. Molarity = moles/volume. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters.
- Step 2: Calculate the Volume of HCl needed. Molarity = moles/volume. Volume = moles/Molarity. Volume = moles H+/0.075 Molarity.
