After the chemical reaction, a salt is produced and water. For example:
HCl (aq, acid) + NaOH (aq, alkaline) → H
2O (water) + NaCl (aq, salt)
It will neutralise the alkali and then turn the liquid to an acid.
When an alkali is added to an acid, the pH increases as the acid is neutralized by the base. This reaction forms water and a salt. The pH ultimately depends on the strength of the acid and the alkali.
Neutralization
Neutralization of the acid, creating water and a salt.
it changes its colour into red.
When an alkali tablet, such as an antacid, reacts with stomach acid (hydrochloric acid), it neutralizes the acid by forming water and a salt. This reaction helps to alleviate symptoms of acid indigestion or heartburn by reducing the acidity in the stomach.
When an alkali (base) and an acid are mixed, they undergo a neutralization reaction where the hydrogen ions from the acid combine with the hydroxide ions from the alkali to form water. This reaction produces a salt as a byproduct. The result is a solution that is closer to neutral pH.
When an acid is mixed with an alkali, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The acidity of the acid decreases and the alkalinity of the alkali decreases as they react with each other.
When acid is added to an alkali, the pH decreases or goes down. This is because the acid donates hydrogen ions (H+) to the alkali, neutralizing the alkaline properties and shifting the pH towards neutrality or acidity.
