What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?
A neutral solution of about 7 pH.
Barium hydroxide contained 2.74g in 100cm of water titration of 20cm required 18.7cm of a hydrochloric acid solution for complete neutralization what is the molarity of the barium hydroxide?
To find the molarity of the barium hydroxide solution, first calculate the number of moles of hydrochloric acid used in the titration. Then use the stoichiometry of the reaction to determine the number of moles of barium hydroxide present. Finally, divide the moles of barium hydroxide by the volume of the solution in liters to get the molarity.
In a titration when the number of moles of hydrogen ions equals the number of moles of hydroxide ions what is said to have happened?
When the number of moles of hydrogen ions equals the number of moles of hydroxide ions in a titration, it means that the solution has reached the equivalence point. At this point, the solution is neutral and the pH is typically around 7, indicating that the acid and base have reacted completely with each other.
What volume of a 0.550 M solution of potassium hydroxide can be made with 10.7g of potassium hydroxide?
To calculate the volume, first find the number of moles of potassium hydroxide using its molar mass. Then use the molarity to calculate the volume. Calculate moles of KOH: 10.7g / 56.11g/mol = 0.191 moles KOH Volume = moles / Molarity = 0.191 moles / 0.550 mol/L = 0.348 L = 348 mL
You have a sample of 1.25 g of magnesium hydroxide MgOH 2 How many moles of magnesium hydroxide are there?
0.0214 mol
What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?

How many moles of hydroxide are in 18.00 mL of 0.1123M NaOH?
Molarity = moles of solute/Liters of solution (18.00 ml = 0.018 Liters)0.1123 M NaOH = X moles solute/0.018 L= 2.021 X 10 -3 moles NaOH============================as all is one to one,2.021 X 10 -3 moles OH -==================
How many moles are in 98.3 molecules of aluminum hydroxide AL(OH)3?
To convert from molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). Therefore, 98.3 molecules of aluminum hydroxide would be approximately 0.163 moles.

How many moles are in 4.75g of sodium hydroxide?
To find the number of moles in 4.75g of sodium hydroxide, you first need to determine the molar mass of sodium hydroxide (NaOH), which is about 40g/mol. Then divide the given mass (4.75g) by the molar mass to obtain the number of moles: 4.75g / 40g/mol = 0.119 moles of NaOH.
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.

How many moles of calcium hydroxide are needed to react with 5.88 mL of nitric acid?
To determine the number of moles of calcium hydroxide needed to react with the nitric acid, you would need to know the concentration of the nitric acid. With the concentration, you can use the balanced chemical equation of the reaction to calculate the moles of calcium hydroxide required.
What is number of moles in 417.6 grams of Barium Hydroxide?
To find the number of moles in 417.6 grams of Barium Hydroxide, first calculate the molar mass of Ba(OH)2, which is 171.35 g/mol. Then, divide the given mass by the molar mass to get the number of moles: 417.6 g / 171.35 g/mol = 2.44 moles.
Determine the number of moles of sodium hydroxide produced when 2 moles of sodium and 3 mol of water react to form soduim hydroxide and hydrogen gas?
Na +H2O -> NaOH +(1/2)H2 Every mole of Sodium requires one mole of water to make one mole of Sodium Hydroxide. So two moles of Sodium will produce two moles of Sodium Hydroxide. If there are three moles of water in the initial reaction then there will be one mole of water left over after reacting with two moles of Sodium. This reaction will produce half a mole of hydrogen gas.
What is the number of moles of sodium hydroxide NaOH corresponding to 10.84 and times 1023 formula units of NaOH?
To find the number of moles of NaOH, you need to divide the given number of formula units by Avogadro's number (6.022 x 10^23). Therefore, the number of moles of NaOH is 10.84/6.022 ≈ 1.8 x 10^-23 moles.
