Does an acid contain one or more hydroxide ions?
An acidic solution contains many more H+ ions than OH- ions, and a basic solution has more OH- than H+. A pure water solution, which is neutral, has exactly equal number of each.
How many grams of magnesium hydroxide required to make 1M of the solution?
the formula is no. moles is mass / molecular mass. As the number of moles is 1, the mass required will be exactly the same as the molecular mass, which is 58.32g
What is the molarity of a solution in which 58 g of NaCl are dissolved in 1.0 L of solution?
Almost exactly 1 M - to be exactly 1.0M would require 58.5 g NaCl
When an acid solution exactly neutralizes a base solution which acids combination always produces a mixture with a pH less than and 82397?
The neutral point is 7,00.
How many moles of hydroxide ion are there in a 250 mL sample of 5.00 M solution of sodium hydroxide?
n=c/v n=3M/.25L n=12 mol m=Mxn m=58.443 g/mol x 12 mol m=701.3 g n= mol c=concentration v=volume m=mass M= molar mass Tylerops: I don't agree with this answer. Molarity is defined as Moles/Liters. In other words Molarity is the concentration of a solution. In the above n= Concentration / Liters. That is equal to saying Moles=(Moles/liters)/ Liters. In the above question the concentration is (3 moles/ liter), or 3M. Plus, how can it be possible to have 12 moles in 250ml when you only have 3 moles in each liter of the original solution? Correct ANSWER: 3.00 M, or 3 moles per (L) "liter" calls for having 3 moles per liter of the solution. The question asks how many moles must be in 250ml of a solution that has 3 moles per Liter. You must ask yourself what percent of 1 Liter is 250mls? Since there are a thousand ml in one liter, (1000ml=1L), then 250ml is exactly 25% of a Liter, or .25L. So, 250ml can only hold 25% of the 3.00 Molarity. Meaning that you multiply 3 x .25 and get .75 moles. 58.443g/molNaCl x .75 moles = FINAL ANSWER 43.83225g NaCl, Sig Fig, 43.83gNaCl
Will exactly one mole of calcium hydroxide neutralize exactly one mole of phosphoric acid?
No, because one mole of calcium hydroxide constitutes two equivalents of calcium hydroxide for neutralization, but one mole of phosphoric acid constitutes three equivalents of phosphoric acid for neutralization. Therefore, one mole of calcium hydroxide will neutralize only 2/3 of one mole of phosphoric acid.
How many milliliters of a 7 percent solution of sodium hydroxide can be made from exactly 35.0 g?
The answer is 500 mL.
What is an example of a solution for science?
Try 1 molar sodium hydroxide NaOH solution and 1 molar hydrochloric acid solution HCl . Mix them together and you have a common salt solution NaCl in water. Not exactly sure what you wanted, but there you go.
Give a name of a substance which could be used to neutralise the water?
Water is usually neutral. In the event that the water is acidic, it can be neutralized by adding a base. Calcium Hydroxide is an example of a basic substance.
Does an acid contain one or more hydroxide ions?
An acidic solution contains many more H+ ions than OH- ions, and a basic solution has more OH- than H+. A pure water solution, which is neutral, has exactly equal number of each.
How can you neutralize a salty solution?
You don't exactly neutralize it. Neutralization is a specific reaction involving acids and bases (see the Related Questions to the left).You can remove the salt by various desalination processes, such as distillation or reverse osmosis.
What can replace sodium hydroxide solution?
That depends entirely on what you want it to do. Nothing can fully replace another solution, because nothing is exactly the same, but other bases can be used for neutralisation or for alkalinity purposes; other sodium salts can be used to provide it if needed.
How do you prepare 30mL of 1 M NaOH solution?
In order to prepare exactly 30 mL of 1M NaOH solution, a volumetric vessel that contains exactly 30 mL when full to a marked level will be needed. By definition, a 1 M solution contains one mole in a liter of volume, and since solutions are homogeneous, 30 mL of such a solution will require (30/1000) mole of sodium hydroxide. The molar mass of NaOH is about 40, corresponding to 1.2 grams of sodium hydroxide, which can be determined by weighing solid sodium hydroxide, dissolving the weighed amount in a volume of water less than the 30 mL capacity of the volumetric vessel, transferring this more concentrated solution into the volumetric vessel, and diluting with pure water until the 30 mL volume is contained in the vessel.
How many grams of magnesium hydroxide required to make 1M of the solution?
the formula is no. moles is mass / molecular mass. As the number of moles is 1, the mass required will be exactly the same as the molecular mass, which is 58.32g
Is sodium hydroxide a molecule?
Not Exactly. It is a compound constructed of a sodium ion (Na+) and a hydroxide ion (OH-). Brought together by electrostatic attraction between the two.
