Sodium chloride is dissolved in water and dissociated in ions.
In a water solution: a mixture of dissolved NaCl and hydrochloric acid.
Any reaction occur.
Nothing much happens.
Nothing
Hydrogen is released and sodium chloride&sodium hydroxide remain in solution.
Any reaction between sodium chloride and sodium hydroxide.
Since Sodium Hydroxide is a base and hydrochloric acid is an acid, you will make water and sodium chloride.
you get salt water which is called sodium hydroxide You get sodium hydroxide as stated above but NOT salt water as this is sodium chloride in water which has the formula NaCl and not NaOH.
When you mix the solutions of Sodium Hydroxide and barium chloride then a double replecement occurs.2 NaOH + BaCl2 = 2 NaCl + Ba(OH)2
Sodium chloride is the product of the reaction between sodium hydroxide and hydrogen chloride.
Magnesium hydroxide, a precipitate, is formed.
sodium lactate
no change
Sodium phosphate is obtained.
kaboom!
