How many moles of KOH are needed to exactly neutralize 500. mL of 1.0 M HCl?
1 mole of HCl reacts with 1 mole of KOH. Therefore, 0.5 moles of KOH (500 mL = 0.5 L) are needed to neutralize 0.5 moles of HCl.
How do you prepare 500 ml 1N hcl from 10N HCl?
To prepare 500 ml of 1N HCl from 10N HCl, you need to dilute the 10N HCl with distilled water. Use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the volume of the initial concentration needed, C2 is the final concentration, and V2 is the final volume. In this case, the calculation would be 10 x V1 = 1 x 500. Solve for V1 to find the volume of 10N HCl needed, then add distilled water to make a total volume of 500 ml.
How do you determine the number of kilograms of CaCO3 needed to neutralize 500 L of 1.40 M HCl?
To determine the number of kilograms of CaCO3 needed to neutralize 500 L of 1.40 M HCl, you can follow these steps: 1. Calculate the number of moles of HCl in 500 L solution. 2. Use the balanced chemical equation between CaCO3 and HCl to determine the mole ratio between them. 3. Calculate the number of moles of CaCO3 needed. 4. Finally, convert the moles of CaCO3 to kilograms using its molar mass.
How can you make 500ml of 0.8M HCl solution from 10M HCl and water?
To make 500ml of 0.8M HCl solution from 10M HCl, you will need to dilute the 10M HCl solution. Calculate the volume of 10M HCl required to make 500ml of 0.8M solution using the dilution formula C1V1 = C2V2. Measure the required volume of 10M HCl, then add water to make up to a total volume of 500ml.
What is the molality of a solution that contains 31.0 grams of HCl in 500 grams of water?
The molar mass of HCl is 36.46 g/mol. First, we convert grams of HCl to moles: 31.0 g HCl / 36.46 g/mol = 0.85 mol HCl. Next, we calculate the molality using the formula: molality = moles of solute / kg of solvent molality = 0.85 mol / 0.5 kg = 1.7 mol/kg.
How many moles HCl in 8.3 g HCl?
There are 0.224 moles of HCl in 8.3 g of HCl. This is calculated by dividing the mass of HCl by its molar mass (36.46 g/mol).
How 1m hcl is equal to 1n hcl?
1M HCl means there is 1 mole of HCl in 1 liter of solution. To convert to 1N HCl, you need to consider the equivalent weight of HCl, which is its molecular weight as it is a monoprotic acid. So, in this case, 1M HCl is equivalent to 1N HCl.
What is the symbol for hydrochloric acid?
The chemical formula (not symbol) of hydrogen chloride is HCl; for a diluted solution you can use "HCl dil." but this isn't a standard formula.
Is 1 m HCl is more reactive than 4m HCl?
1 m HCl is not more reactive than 4m HCl, but 4m HCl is more concentrated.
What product do all neutralization reactions have in common?
All neutralization reactions involve the formation of water as a product, along with a salt.
Is hcl in organic?
No, HCl is a mineral acid
What was done in the experiment to ensure that all KHCO3 was react?
In the experiment, excess HCl was added to the solution containing KHCO3. This ensured that all of the KHCO3 would react completely, as any unreacted KHCO3 would still be neutralized by the excess HCl.
