How do you make a 0.1 M solution of HCl?

Preparation and Standardization of 0.1 M Hydrochloric acid (HCl)

1. Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask.
2. Add about 8.5 ml of Conc.
3. Add more about 700 ml of water, mix and allow to cool to room temperature.
4. Make up the volume 1000 ml with water.

How many ml of 0.1 M HCl are required to react with 0.01 mole of na2co3 the products are nacl and h2co3?

Hence, 158 mL of 0.1 M of HCl is required to react completely with 1 g mixture of Na2CO3 and NaHCO3, containing equimolar amounts of both.

What is a 0.1 M solution?

A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre. To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.

What does 0.1 m mean in chemistry?

Both m and M are units of the concentration of a chemical solution. Uppercase M is molarity, which is moles of solute per liter of solution (not solvent). A solution using this unit is termed a molar solution (e.g., 0.1 M NaCl is a 0.1 molar solution of sodium chloride).

What is pH of 1 M HCl?

zero
The pH of 1 M hydrochloric acid is zero. The reason is that pH is defined as negative 1 times the log base 10 of [H+], or the proton concentration in moles per liter.

What is the pH of O 1 M HCl?

1.083
The pH of the 0.1 molar HCl solution is 1.083 (rather than 1.0 as often assumed).

How many ml of 0.1 M HCl are required to react completely with 1 gram mixture of any two three and NaHCO3 containing equimolar amounts of both?

Therefore, the amount of HCl required is 158mL.

How much HCl is required to neutralize NaOH?

To neutralise 20- ml of 0.02M NaOH, the volume of 0.1M HCl required = 20 x 0.02/0.1= 4- ml. Let us consider the titration of HCl against NaOH. Let us take 20- ml of 0.02 M NaOH in a conical flask and add a drop of phenolphthalein indicator.

How to prepare phenolphthalein indicator with NaOH and HCl?

Let us take 20- ml of 0.02 M NaOH in a conical flask and add a drop of phenolphthalein indicator. The solution will turn pink in colour. The pH of this solution will be = [ pOH= – log (0.02)= 1.6990]= 12.3010. On adding 1- ml of 0.1M HCl, into the conical flask, the total volume will be 21- ml.

How much water is needed to make 1 mol HCl solution?

Therefore, to create the 0.1 M solution, you need to add 9 Liters water in relation to 1 mol HCl. If you want one liter of 0.1 M solution, take 0.1 L of the 1 M solution and pour in 0.9 L water. If you want 100 L of the 0.1 M solution, take 10 L 1 M solution and pour in 90 Liters water.

How do you find the pH of hydrochloric acid?

Hydrochloric acid (HCl) is a common acid used in the laboratory to make acidic solutions. Aqueous HCl solutions show low pH values because HCl is a strong acidic compound. You can easily check this by using a pH meter. In theoretically, pH value can be found by substituting concentration of HCl in the pH equation.
