What color would a phenolphthalein solution be at ph=11 ?

Colurs of Phenolphthalein at different pH's are as follow,

When pH is less than zero, means when the conditions are strongly acidic then it imparts Orange Color.

At pH ranging from zero to 8.2 (acidic or weakly acidic conditions) it is colorless.

At pH ranging from 8.2 to 12 (Basic conditions) it imparts Pink color.

At pH greater than 13 (strongly basic) it is again Colorless.

Result:
           So, At pH = 11 phenolphthalein solution gives Pink Color.

The reaction will shift to the right

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
