When just enough strong acid (e.g. HCl) is used to neutralize a strong base (NaOH), the pH should be neutral (pH = 7.0).
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
how much sodium hydroxide in grams must be added to seawater to precipitate 86.9mg of magnesium present?
It turns yellow
Endothermic
Copper metal itself does not react with sodium hydroxide. But when NaOH is added to a solution of copper ions, it would form a light blue precipitate, which is copper(II) hydroxide, and will NOT dissolve with the excess alkali.
Green
Sodium react with water forming a base - sodium hydroxide - and releasing hydrogen. Add an acid for neutralization.
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
There are times when bacteria, acidify an infected site, therefore adding sodium hydroxide will neutralize the region for a basic site.
Sodium hydroxide simply becomes ionized in water, no reaction will occur. And the concentration of NaOH will be reduced, if enough water is added.
No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.
