# Quick Answer: How Do I Make A 50% HCl Solution?

## How do you make a 10% HCl solution?

Take 10 mL of HCl and mixed with 90 mL of Distilled Water.

(Take Water first i.e.

in 90 mL of water add 10 mL HCl) it will give you 10% v/v HCl.

If you have solid HCl (powder) then for 100 mL, Take 10 gm of HCl powder then add 100 mL water..

## How do you make 40% NaOH?

To prepare a 40%NaOH solution you weigh 40 gm NaOH and dissolve it in 100 ml water. To prepare 1 M you dissolve the molecular weight of it in one L. The molecular weight of NaOH is 23+16+1=40 gm.

## How do you make a 1% solution?

The mass of a solute that is needed in order to make a 1% solution is 1% of the mass of pure water of the desired final volume. Examples of 100% solutions are 1000 grams in 1000 milliliters or 1 gram in 1 milliliter.

## How do you make 2 normal HCl?

2N HCl. Prepare 1 L of 2N HCl by mixing 834 ml of deionized water and 166 ml of concentrated 12N HCl. This solution is stable at room temperature. Caution: This solution should be prepared under a hood with the HCl slowly being added to the deionized water.

## What is a 2% solution?

2% w / w solution means grams of solute is dissolved in 100 grams of solution. Weight / volume % 4% w / v solution means 4 grams of solute is dissolved in 100 ml of solution. Volume / weight % 3% v/ w solution means 3 ml of solute is dissolved in 100 grams of solution.

## How do you get 10% HCl from 37 %?

So, we need 135.15 mL of 37% HCl to mix with 364.85 mL of water to produce 500 mL of 10% HCl. So, we need 135.15 mL of 37% HCl to mix with 364.85 mL of water to produce 500 mL of 10% HCl. We should always fill the container with water before HCl to avoid spontaneous heat changes.

## How do you make HCl solution?

1M HCl: add 1mol/12M = 83 ml conc. HCl to 1L of water or 8.3ml to 100ml.2M HCl: add 2mol/12M = 167 ml conc. HCl to 1L of water or 16.7ml to 100ml.

## What is a 10% solution?

A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution. Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water. … A 10% of alcohol solution by volume has ten ml of alcohol dissolved in 100ml of solution.

## What does 5% w/v mean?

Another variation on percentage concentration is weight/volume per cent or mass/volume per cent. This variable measures the amount of solute in grams but measures the amount of solution in millilitres. An example would be a 5%(w/v) NaCl solution. It contains 5 g of NaCl for every 100. mL of solution.

## What is a 50% solution?

50% (w/v) NaCl would be 50 grams in 100 mL of water. … I always interpreted that to be 50 grams of NaCl in 100 mL of solution (solution = water + salt).

## Can you dilute hydrochloric acid with water?

Even though strong solutions of HCl may not react in a violent, exothermic reaction when diluting with water, (such as sulfuric acid), it is always recommended to dilute strong acids by adding them to larger volumes of water.

## How do you make a 50 percent HCl solution?

Add 8.26 mL of concentrated HCl to about 50 mL of distilled water, stir, then add water up to 100 mL. Mass percent solutions are defined based on the grams of solute per 100 grams of solution. Example: 20 g of sodium chloride in 100 g of solution is a 20% by mass solution.

## How do you make a 50% solution?

Take 1000 ml water in a conical flask. As the molecular weight of NaOH is 40 so to make 50% solution take 20 gm of that NaOH into the water. agitate that solution and then you will get 50% NaOH solution .

## What is a 1% solution?

In biology, the “%” symbol is sometimes incorrectly used to denote mass concentration, also called “mass/volume percentage.” A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as “1%” or “1% m/v” (mass/volume). … Thus 100 mL of water is equal to approximately 100 g.

## How do you calculate dilution?

Example 2: Suppose you must prepare 400 ml of a disinfectant that requires 1:8 dilution from a concentrated stock solution with water. Divide the volume needed by the dilution factor (400 ml / 8 = 50 ml) to determine the unit volume. The dilution is then done as 50 ml concentrated disinfectant + 350 ml water.
