They are not comparable. Sulfuric acid is corrosive to some other material then Sodium hydroxide and vice verse.
They would not react each other and would result in an alkaline solution.
Add concentrated solution of Hydro chloric acid to the solution of sodium hydroxide till mixture becomes neutral (checked by litmus) then heat the mixture , when a little amount of water is left allow to cool the mixture , the crystals of sodium chloride settelted down filter and dry the crystals.
It can be either. Two examples would be: Caustic soda (Sodium Hydroxide), which is very alkaline. Caustic potash (Potassium Hydroxide), which is very acidic.
Hydrochloric Acid would be the stronger acid, as Sodium Hydroxide is an alkali.
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.
NaOH is a base so it will produce a pH above 7.
Yes, as it will serve to dilute the concentration of the sodium hydroxide being placed in the buret. You will being adding a known concentration of sodium hydroxide and ending up with an unknown concentration.
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.
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.

Zinc salt will form complexes of sodium zincate which is colourless and a clear solution would be observed

Actually a 50% solution of sodium hydroxide would be made using enough water to total 100 mL of solution if using sodium hydroxide pellets or crystals. 50% of the total weight of the solution not 50% of the weight of the water used. As suggested by the first answer, the solution would be about a 33% solution. percentage solutions are weight for weight. Therefore 50% solution would be 50g of sodium hydroxide dissolved in 100g (100mL) of water.
