As soda contains carbon dioxide, it's actually a dilute solution of carbonic acid, hence phenolphthalein remains colourless.
Washing soda is sodium carbonate and phenolphthalein will be pink in colour in a solution of washing soda.
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
Phenolphthalein is a pH indicator that turns pink in alkaline solutions with a pH greater than 8.2. Baking soda (sodium bicarbonate) is basic, so when phenolphthalein is added to a solution containing baking soda, it will turn pink.
Phenolphthalein turns pink/magenta in the presence of an alkali.
Phenolphthalein is the indicator that turns pink in alkaline solutions it WILL NOT show any colour in an acid environment!!

Phenolphthalein is colorless in sulfuric acid.
Alkalis turn phenolphthalein pink or magenta.
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
Oxalic acid is a weak acid and phenolphthalein is a pH indicator that changes color in the pH range of 8.2 to 10. Oxalic acid solutions typically have a pH below the range where phenolphthalein changes color, so there is no visible change when phenolphthalein is added to oxalic acid.
Phenolphthalein would turn pink in a borax solution, indicating the solution is basic. Borax acts as a weak base in solution and would cause phenolphthalein to change color due to its alkaline nature.
Phenolphthalein turns pink in a base and turns colourless in a base
