Would it take more HCl or h2so4 to neutralize NaOH?
It would take more of the 0.1 M HCl. Sulfuric acid has two protons per molecule, so it takes half as much of the 0.1 M H2SO4 to neutralize the sodium hydroxide.
Why does h2so4 require more NaOH for neutralization?
If both acids have the same molarity, then sulfuric acid requires twice the volume of NaOH during a titration because sulfuric acid contains twice as many hydrogen atoms (two hydrogen atoms per molecule compared to one hydrogen atom per molecule in nitric acid).
What volume of NaOH is required to neutralize the HCl?
about 2.5 L
Therefore, we will need about 2.5 L of sodium hydroxide to neutralize the hydrochloric acid.
Why does sulfuric acid need more sodium hydroxide to turn phenolphthalein pink than nitric acid?
Because sulfuric acid is a strong acid and sodium hydroxide is a strong base, the phenolphthalein will turn pink because the solution has become more basic. The pH will become more neutral, but will be dependent on the concentration of each substance.
What happens when H2SO4 reacts with NaOH?
NaOH + H2SO4→ Na2SO4 + H2O .

What is the volume of HCl solution?
If 13.7 mL of hydrochloric acid solution is taken, then [13.7 mL x (1.18 g/mL) = 16.2 g is the mass of the hydrochloric acid solution….Calculations for synthetic reactions where a strong mineral acid is used.
| Reagent | Density (g/mL) |
|---|---|
| HCl | 1.18 |
| HNO3 | 1.41 |
| H2SO4 | 1.84 |
| CH3CO2H | 1.06 |
How do you determine the volume needed to neutralize a solution?
So, the solution will be neutralized when the number of moles of H+ equals the number of moles of OH-.
- Step 1: Calculate the number of moles of OH-. Molarity = moles/volume. moles = Molarity x Volume.
- Step 2: Calculate the Volume of HCl needed. Molarity = moles/volume. Volume = moles/Molarity.
What happens when phenolphthalein is added to sodium hydroxide solution?
Explanation: When the sodium hydroxide, which is a base, is mixed with phenolphthalein, it turns pink. This happens because the base is neutralized in an acid solution, which causes the indicator to become colorless. All of the base is neutralized by the citric acid.
What happens when sulfuric acid reacts with sodium hydroxide?
When sodium hydroxide react with sulphuric acid they form Sodium sulphate and water. The reactants is base and an acid, which leads to neutralization process and yields a salt .

What is the indicator used when H2SO4 is titrated with NaOH?
The indicator dye used in this experiment is call “bromothymol blue”. Add 3 or 4 drops of bromothymol blue to the acid solution in the 250 mL beaker. The indicator should turn yellow in the acid solution.
Why does HCL have a lower normality than H2SO4?
HCl will require more volume, because HCl has a lower normality than H2SO4. Normality in acid-base solutions expresses how many moles of protons or hydroxide exist in an acid or base. Normality equals the molarity of the acid times the volume of the acid times the number of hydrogen or hydroxide ions of the acid or base.
What is the difference between molarity and normality of NaOH?
Molarity goes by the entire formula, in this case HCl or H2SO4 respectively, while normality goes by the “business part” of the formula, in this case the H equivalents. A solution of H2SO4 is twice the normality of its molarity, to reflect the fact that it takes only half as many moles as of HCl to neutralize the NaOH.
How many molecules of NaOH can HCl neutralize?
So from that it should become clear that each molecule of HCl can neutralize one molecule of NaOH: H2S04 + 2NaOH → Na2SO4 + 2H2O. From there it is apparent that you need less volume of H2SO4 because they have the same number of moles/litter in this problem.
What is meant by normality in acid base solutions?
Normality in acid-base solutions expresses how many moles of protons or hydroxide exist in an acid or base. Normality equals the molarity of the acid times the volume of the acid times the number of hydrogen or hydroxide ions of the acid or base.
