Why does the phenolphthalene turns pink in barium hydroxidE?
Phenolphthalein turns pink in barium hydroxide because barium hydroxide is a strong base, which raises the pH of the solution. Phenolphthalein is an acid-base indicator that is colorless in acidic and neutral solutions but turns pink in alkaline conditions, typically at a pH above 8.2. The presence of hydroxide ions from barium hydroxide causes this color change, indicating a basic environment.
Why does the phenolphthalein turn pink in barium hydroxide?
Phenolphthalein turns pink in barium hydroxide because barium hydroxide is a strong base, which raises the pH of the solution. In basic conditions (pH above 8.2), phenolphthalein changes from colorless to pink due to the deprotonation of its phenolic hydrogen, resulting in a conjugate base that absorbs light in the visible spectrum. This color change indicates the presence of hydroxide ions, which are characteristic of strong bases like barium hydroxide.
What is the anhydride of barium hydroxide?
The anhydride of barium hydroxide is barium oxide (BaO). It is formed when barium hydroxide is heated to remove water molecules and only the oxide remains.
Is barium hydroxide a molecular compound?
Barium hydroxide is a molecular compound.
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.

What is sodium hydroxide in a PH scale?
Sodium Hydroxide or NaOH is a highly basic compound. On the pH scale it has a pH of 14.

What is the name for Ba(OH)2?
Ba is Barium, OH is Hydroxide and the 8 H2O is Octahydrate. This results in Barium Hydroxide Octahydrate.
How much does calcium hydroxide has on a pH scale?
10
What's the the strongest base on the pH Scale?
The strongest base is the hydroxide ion, in the pH scale 0 to 14.
Is barium hydroxide a cation or an anion?
Barium hydroxide is not a cation or an anion. It is a compound. It is made of barium ions and hydroxide ions.
What is the name for BaOH?
Barium hydroxide
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
The solution turns pink when a drop of phenolphthalein is introduced in barium hydroxide. Phenolphthalein is a pH indicator that changes color in the presence of alkaline solutions, indicating the basic nature of barium hydroxide.
Does the pH scale measure the concentration of hydroxide ions?
Yes, if you use a little bit of math. Take 14 minus your pH and you get the negative decadic logarithm of the hydroxide concentration.
Is Barium hydroxide insoluble in water?
No, barium hydroxide is soluble in water. When dissolved in water, it dissociates into barium ions (Ba²⁺) and hydroxide ions (OH⁻).
What is the name of the precipitate formed when barium chloride react with sodium hydroxide?
The precipitate formed when barium chloride reacts with sodium hydroxide is barium hydroxide (Ba(OH)2).
