The reaction below is an acid-base reaction. HCl + NaOH --> NaCl + H2O

The solutions of each substance, both reactants and products, are colourless, so there is no colour change observed in this reaction. However, if a pH indicator is used, a colour change is observed.

A pH indicator changes colour depending on the pH of the solution, and thus the solution changes colour. If the solution is acidic and Universal Indicator is used, it is red, orange or yellow, depending on the pH. If it is alkaline, it is blue or violet. If, however, it is neutral, neither acidic nor alkaline, it is green.

If we add Universal Indicator to NaOH, sodium hydroxide, it turns blue. If we add it to HCL, hydrochloric acid, it turns red. If the HCl and NaOH are present in equal amounts, the two solutions will mix to give a neutral solution, which turns the Universal Indicator green.

Does HCl change in concentration when neutralized with NaOH?

Yes, when HCl is neutralized with NaOH, the concentration of HCl decreases as it reacts with NaOH to form water and NaCl. The concentration of the resulting NaCl solution will increase as the reaction progresses.


Combination of HCl and NaOH?

When hydrochloric acid (HCl) and sodium hydroxide (NaOH) are combined in water, they react to form water (H2O) and sodium chloride (NaCl), which is table salt. The reaction is exothermic, meaning it releases heat. The equation for this neutralization reaction is: HCl + NaOH -> NaCl + H2O.

Is naoh plus hcl equals h2o plus nacl a doulbe replacement?

Yes, the reaction between NaOH and HCl forms water (H2O) and sodium chloride (NaCl) through a double displacement reaction. The sodium ions from NaOH swap places with the hydrogen ions from HCl, resulting in the formation of water and sodium chloride.


Is adding NaOH to HCL chemical or physical change?

When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
