You can't because you do not have a concentration for the acid. The reaction is two alkali reacts with one acid.

The absorbance of a solution of NiCl2 of unknown concentration is found to be 0.388 what is the concentration of this soultion?
684
How do you find the concentration of potato cells immersed in salt solutions?
You would have to use a spectrophotometer to measure the absorbance of your unknown solution. But first, you need to make several solutions with known concentrations. Measure the absorbance of the known concentrations and plot them on an X and Y axis where X equals concentration and Y equals absorbance. Do a best-fit line for your data. Measure the absorbance of your unknown solution. Find this value on your Y-axis and find out where this value intersects with your line of best fit. The X value at the intersection is your concentration of potato cells. By the way, make sure you use the same wavelength throughout the experiment.
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
What is the weight in grams of a 0.5 N Na2CO3 used in determining the concentration of unknown HCl solution?
A 0.5N Na2CO3 used in determining the concentration of an unknown HCl solution has a weight of 1.06 grams. To find the weight, you need to first find out how many moles there are by calculating molarity times volume.
What is the process of standardization?
Standardization is a term that can be used in many fields. A chemist would use standardization when trying to figure out the concentration of an unknown solution. They need to know the specific concentration of one of the solutions so they can calculate the other unknown concentration. Many acid-base reactions use this technique. They perform a series of repeatable tests with a third chemical solution that never varies in concentration. They can then calculate the one concentration and use it in their experiment to determine the other concentration. This set of tests is known as standardization of a solution.
Which of the unknown colorless solutions are acidic?
Which of the unknown colorless solutions is (are) acidic
Two clear solutions are placed in separate beakers the first solution as a pH of 4 and the pH of the second is unknown if the two solutions are mixed and the resulting pH is 5 the second solution must?
a higher concentration of OH- ions
Who invented algebra when why?
its origins go back to the ancient Babylonians by using this system they were able to apply formulas and calculate solutions for an unknown value or values and i guess it was passed form there
The absorbance of a solution of NiCl2 of unknown concentration is found to be 0.388 what is the concentration of this soultion?

How do I identify relative concentrations of solutions vs cells in an experiment?
If you place the cells in the unknown solution and it shrinks/shrivels up, then the unknown solution is hypertonic. That means it has higher concentrations of permeable ions than does the cell. If the cell ruptures/bursts, then the opposite is true. In that case, the unknown solution has a lower concentration of ions (hypotonic). If nothing happens to the cell and it maintains the original morphology, then the unknown solution is isotonic and has approximately the same ionic concentration as inside the cell. These observations are based on the principle of osmosis.
What is titration used in the medicine industry?
Medicine is uses to reduce a patient until they are heal. In particularly in chemistry is it the process of finding a concentration of a certain reactants in solutions. This functionality, titration is also known as volumetric analysis, due to a heavy reliance on the measurement of volume and concentration. Titration involves taking an agent of unknown concentration and adding it to a solution. The agent is often known as the titrant and the purpose of adding it o a solution is to create a measurable reaction with the unknown agent. The scientists have to find the exact concentration of unknown agent, also known as the analyte. The concentration of the analyte will not found until the reaction has finished. Often the solution that will change colour to give and assessable endpoint to the reaction.

What is the optimum concentration of amylase?
it is unknown im afriad
Why is a titration performed?
To find the unknown concentration of a sample by using a reagent with a known concentration. ( IE; molarity )
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
Can you titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer?
yes you can, however you need the chemical coumpound name, how many grams of that chemical compound was used, and the litres that it was mixed with. for example: 2g of NaF was used to mix in a 1L solution (NaF has a molas mass of about 42g) 2g of NaF x 1 mol/42g (grams cancel and left with mols) 0.048mol/1L = 0.048mol/L conentartion
