Hydroxide solution turns universal indicator blue because it is a strong base with a high concentration of hydroxide ions. These hydroxide ions react with the indicator molecules, causing a color change to blue. On the other hand, alkane solutions do not contain hydroxide ions and are typically neutral or slightly acidic, so they do not cause the indicator to turn blue. **

Hydroxide solution turns the universal indicator blue because it is a basic solution. Basic solutions have a higher concentration of hydroxide ions (OH-) which react with the indicator to produce a blue color. On the other hand, alkane solutions are neutral and do not have a significant concentration of hydroxide ions, so they do not cause the universal indicator to turn blue. **
