Is phenolphthaleine an acid or base?

I think it is neutral


When a acid reacts with an alkali what are the twp products are formed what are they?

When an acid reacts with an alkali, the two products formed are salt and water. This reaction is called neutralization, where the acid donates a proton (H+) to the alkali to form water, and the remaining ions from the acid and alkali combine to form a salt.


What is the reaction between an acid and an alkali to produce a salt and water?

The reaction between an acid and an alkali is called neutralization. In this process, the hydrogen ions (H+) from the acid combine with the hydroxide ions (OH-) from the alkali to form water (H2O). Simultaneously, the remaining ions from the acid and alkali react to form a salt. This reaction can be represented by the general equation: Acid + Alkali → Salt + Water.


Is sulfuric acid an alkali metal?

No, sulfuric acid is not an alkali metal. It is a strong mineral acid with the chemical formula H2SO4, composed of hydrogen, sulfur, and oxygen. Alkali metals are a group of elements in the periodic table that includes lithium, sodium, potassium, and others.


What is the normality of an acid solution if 50 ml of the solution requires 48.6 ml of 0.1879 N alkali for neutralization?

The normality of the acid solution can be calculated using the formula: Normality of acid x Volume of acid = Normality of alkali x Volume of alkali. Plugging in the values, we get: Normality of acid x 50 ml = 0.1879 N x 48.6 ml. Solving for the normality of the acid gives approximately 0.186 N.
