Question 18 Question Score: You got 0 points out of a possible 1 point on this question Radish extract indicator turns to a bright red color in low pH solutions and mustard-yellow in solutions with a high pH value. If a teacher places this radish extract indicator in a NaOH water solution, which of the following accurately explains what will happen? A The indicator will not turn colors because there is an equal Na and OH-ions dissolved water, and the solution is neutral B The indicator will turn bright red becaus OH than OH' ions, and the solution is acidic C The indicator will turn bright because there are more Hions than Nations dissolved in water, and the solution is acidic D The indicator will turn mustard-yellow because there are more OH than H+ ions, and the solution is basic.
