What is the normality of a 0.10 M solution of phosphoric acid?
The normality is o,3.
What is the pH of a solution prepared by mixing 100.00 ml of 0.020 m caoh2 with 50.00 ml of 0.100 m naoh assume that the volumes are additive?
12.97
Derivation of normality?
The normality of a solution is the gram equivalent weight of a solute per liter of solution. For example, 1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles H+ ions.
What is the Normality of H3PO4 solution contains 275g H3PO4 in 120 L of solution?
Calculus with (units) in brackets shows the way how and why.275 (g) / 97.9 (g/mol) = 2.81 mol in 120 L = 2.81 (mol) / 120 (L) = 2.34*10-2 (mol/L) = 0.0234 M H3PO4And since there are 3 protons available per mole: 0.0234 (M) H3PO4 * 3(N/M) = 0.0702 N
What is the molarity of a solution of 3 moles (mol) of FeBr3 in L water?
3 moles in 1 liter = 3 M
What is the normality of a 0.10 M solution of phosphoric acid?
The normality is o,3.
Will CaOH2 precipitate from solution if the pH of a .050 M solution of CaCl2 is adjusted to 8.0?
Will not Precipitate
What is the normality of a 6.35 M H2SO4 is?
0.08 n
Calculate for a solution formed by adding 4.80ml of 0.130 M KOH to 19.0ml of 7.6x102 M of CaOH2?

What is the OH- of a 4.0 x 10-4 M solution of CaOH2?
The concentration of the OH- is 8.0 x 10-4 In terms of molarity, since the hydroxide is double that of the calcium, double the molarity of the solution.
Molarity of a solution of 6 moles mol of NaCl in 2L water?
Molarity = moles of solute/Liters of solution Molarity = 6 Moles NaCl/2 Liters = 3 M NaCl ========
What is the normality of one liter solution if it has 3.65 grams of Hydrochloric acid?
Normality is the number of gram equivalents of solute per liter of solution.N = [ ( m ) / ( M ) ( Z ) ] [ 1000 / V in mL ]where Z represents the number of H+ ions that the one molecule of the solute is capableof releasing or reacting with. For HCl, Z = 1 .N = [ ( 3.65 g ) / ( 36.458 g / mol ) ( 1 ) ] [ 1000 mL / 1000 mL )N = 0.100 N

Calculus with (units) in brackets shows the way how and why.275 (g) / 97.9 (g/mol) = 2.81 mol in 120 L = 2.81 (mol) / 120 (L) = 2.34*10-2 (mol/L) = 0.0234 M H3PO4And since there are 3 protons available per mole: 0.0234 (M) H3PO4 * 3(N/M) = 0.0702 N
What is the normality of a 1.25 M solution of H2SO4?
Sulfuric acid H2SO4 will give away 2 protons H+ for this reason its normality is 2 times its molarity. so for H2SO4 M = 2N For HCl M= 1N because HCl has only one proton H+ H3PO4 for example has 3N = M so for your case, 6M = 2N and N= 6/2 = 3.
What is the normality of commercial grade HCl?
The normality of commercial grade hydrochloric acid (HCl) can vary depending on the concentration specified by the manufacturer. Hydrochloric acid is commonly available in different concentrations, such as 37% or concentrated hydrochloric acid. To determine the normality, it is essential to know the molarity (moles of solute per liter of solution) and the number of equivalents of the acid. Normality (N) is related to molarity (M) by the equation: � = � × � N=n×M where: � N is the normality, � n is the number of equivalents, � M is the molarity. For hydrochloric acid (HCl), which is a monoprotic acid (donates one proton), the number of equivalents ( � n) is equal to 1. Therefore, if you know the molarity of the commercial grade hydrochloric acid, you can determine its normality using the equation mentioned above. It's important to check the product label or contact the manufacturer for the specific concentration of the hydrochloric acid you are using.
