Thymol blue will be yellow at pH < 8
HCl has a pH of 1 so thymol blue would turn red in this acidic condition. Phenolphthalein is colorless in an acid so what you would see would be red.
Because Hydrochloric acid is an acid, phenolphthalein would be clear. In bases Phenolphtlalein becomes pink
Nothing will happen to the Sandstone :D Hope that would help =)

When the hydrochloric acid is dropped on limestone it will start to bubble (which is carbon dioxide). After thirty minutes, there will be CaCl2 and water left on the limestone.
