First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.

How is hornblende formed?
(Ca,Na)2-3(Mg,Fe,Al)5Si8022(OH)2 The general formula for all amphiboles is Si8O22(OH)2
Is ca(oH)2 a acidicalkalin or neutral solution?
Calcium hydroxide, represented as Ca(OH)₂, is classified as a strongly alkaline compound when dissolved in water. It dissociates to release hydroxide ions (OH⁻), which increases the pH of the solution, making it basic. Therefore, a solution of Ca(OH)₂ is alkaline, not acidic or neutral.
What is the normality of a 3 M solution of Ca(OH)2?
The normality of a solution depends on the number of equivalent particles it provides in solution. For calcium hydroxide, Ca(OH)₂, it dissociates into one calcium ion (Ca²⁺) and two hydroxide ions (OH⁻). Therefore, a 3 M solution of Ca(OH)₂ provides 6 equivalents of hydroxide ions per liter. Thus, the normality of the 3 M Ca(OH)₂ solution is 6 N.
What is the pH of a 0.0110 M solution of Ba OH2?
The pH of a 0.0110 M solution of Ba(OH)2 can be calculated by finding the hydroxide ion concentration, which is double the concentration of the Ba(OH)2 solution. Therefore, [OH-] = 2 * 0.0110 M = 0.0220 M. From this, you can calculate the pOH using the formula -log[OH-], and then convert pOH to pH using the relation pH + pOH = 14.
Net ionic equation for precipitation reaction between silver nitrate solution and sodium sulfide solution?

What is the balanced equation for Na plus NaNO3?
This reaction is known as the double exchange reaction Ni(NO3)2(aq) + 2 NaOH(aq) --> Ni(OH)2(s) + 2 NaNO3(aq) (aq) means in aqueous solution (s) means solid, hence nickel hydroxide is seen precipitating out of the solution
What is the pH of a Ca(OH)2 solution?
The pH of a Ca(OH)2 solution is around 12.5, making it basic.

What is NaOH2?
NA(OH)2 is actually sodium hydroxide. The sodium (NA) cation carries a +2 charge, and the hydroxide (OH) anion carries a -1 charge. To balance the equation you must have 2 hydroxide ions to make the anionic charge total -2 to match the cationic +2 charge. It is used to make soaps, cleaners, and hydrogen gas in an aqueous solution when exposed to electrical current. It is a highly corrosive base and should be handled with caution.

How can limewater be made from calcium carbonate?
Limewater can be made by adding calcium carbonate (CaCO3) to water to produce calcium hydroxide (Ca(OH)2). The chemical reaction is CaCO3 + H2O -> Ca(OH)2 + CO2. The resulting solution is limewater, which is commonly used in various chemical tests.
