How many grams of sodium sulfide are formed if 1.90 of hydrogen sulfide is bubbled into a solution containing 2.53 of sodium hydroxide assuming that the sodium sulfide is made in 91.0 yield?

The equation for the reaction specified is 2 NaOH + H2S -> Na2S + H2O. Therefore, if the yield were 100 %, two formula masses of sodium hydroxide are required to produce one formula mass of sodium sulfide. The gram formula mass of NaOH is 40.00 and that of sodium sulfide is 78.04. The specified number of grams of sodium hydroxide corresponds to 2.53/40.00 or 0.06325 formula masses and therefore would provide half this many formula masses of sodium sulfide, for a mass of (0.06325)(78.04)/2.000 or 2.568 grams of sodium sulfide. Since the yield is specified as 91.0 %, the actual amount of sodium sulfide produced is 2.25 grams, to the justified number of significant digits.

A solution containing equal numbers of hydrogen ions and hydroxide ions is called what?
Technically it is called water because the positive hydrogen ions and the negative hydroxide ions would attract to form a compound with two hydrogen molecules and one oxygen molecule. H2O. This occurs most often in acid-base neutralization reaction where water is a product of the reactions.
Does dissolving ammonia in water form acids?
No, it forms a basic solution containing ammonium hydroxide.
What solutions have a greater number of hydroxide ions than hydrogen ions?
An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.
Why does the part of leaf inside the bottle containing potassium hydroxide solution not get carbon dioxide?
i don`t no
What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
Acidic
What is the solution containing equal numbers of hydrogen and hydroxide?
It is a neutral solution, pH = 7.0 at room temp.
A solution containing equal numbers of hydrogen ions and hydroxide ions is called what?

What is the difference in the amount of hydrogen ion and hydroxide ion in the solution with pH7?
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
A neutral solution has an equal numbe of?
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
What is alkaline pottassium permanganate solution?
Alkaline potassium permanganate solution is a solution of potassium permanganate containing an alkali. The alkali can be sodium hydroxide or potassium hydroxide.
A term for solutions containing a majority of hydroxide ions?
Basic solution
The terms base and alkaline refer to solutions that hydronium hydroxide hydrogen?
hydroxide anion, OH-: alkaline solution hydrogen cation, H+; hydronium cation, (H3O)+: acidic solution
Are there are more hydroxide ions than hydrogen ions?
In a solution with a pH higher than 7, there are more hydroxide than hydrogen ions.
What is a solution that contains more hydroxide than hydrogen?
It is a basic solution, pH above 7
How do you make magnesium hydroxide solution?
You make it with magnesium hydrogen and oxygen!
What Is a substance that produces hydroxide ions in solution.?
A base does this. The hydroxide (OH-) ion appears in solution. An acid produces hydrogen (or hydronium) ions in solution, and not hydroxide ions.
What gas is created when you heat up sodium hydroxide solution and ammonium chloride solution?
Hydrogen Chloride
