Full Answer
What is the volume of hydrochloric acid needed to balance the solutes?
This means that in order to have equal numbers of moles of both solutes, you need to have a volume of hydrochloric acid solution that is 3.5 times bigger than the volume of the sodium hydroixde solution. Since the sodium hydroixde solution has a volume of 50.0 mL, it follows that the volume of hydrochloric acid needed will be
How do you dilute 160 Ml of hydrochloric acid?
Expressed in milliliters and rounded to two sig figs, the answer will be This is exactly what the formula for dilution calculations allows you to do So, you would prepare this solution by adding enough water to your 160-mL sample of 0.25-M hydrochloric acid solution to make the total volume of the resulting solution equal to 1.00 L.
How can I determine the concentration of CoCl2(aq) in a sample solution?
A student uses visible spectrophotometry to determine the concentration of CoCl2 (aq) in a sample solution. First the student prepares a set of CoCl2 (aq) solutions of known concentration. Then the student uses a spectrophotometer to determine the absorbance of each of the standard solutions at a wavelength of 510nm and constructs a standard curve.
What is the ratio of HCl to KOH?
Hydrochloric acid, HCl, and potassium hydroxide, KOH, react in a 1:1 mole ratio to produce aqueous potassium chloride, KCl, and water. This means that a complete neutralization requires equal numbers of moles of hydrochloric acid, i.e. of hydronium cations, H3O+, and of potassium hydroxide, i.e. of hydroxide anions, OH−.
How much more concentrated is potassium hydroxide than hydrochloric acid?
In other words, for the same volume of both solutions, the potassium hydroxide solution contains 3.5 times more moles of solu te than the hydrochloric acid solution. This means that in order to have equal numbers of moles of both solutes, ...
