Question

NaOH+фенолфталеїн+HCI=...

Answer 1

Ответ:

NaOH+фенолфталеин- фенолфталеин- станет малиновым

NaOH+HCl+NaCl+H2O-фенолфталеин обесцветится

Answer 2

NaOH + фенолфталеїн + HCl = NaCl + H2O

When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl) in the presence of phenolphthalein, the following reaction occurs:

NaOH + HCl → NaCl + H2O

In this reaction, sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl) to form sodium chloride (NaCl) and water (H2O). Phenolphthalein is typically used as an indicator to show the endpoint of the reaction, changing color from pink to colorless as the reaction progresses.
