Phenolphthalein,Hcl, NaOH, methyl orange , sodium,potassium,water,vinegar
We conducted a lab in class and my teacher gave me a lab report that is due tomorrow. We mixed phenolphthalein into hydrochloric acid and sodium hydroxide. (Turned different colours, except Hcl+pheno.) Then we mixed methyl orange into more hcl and naoh. We had to write our observations. Next she put sodium and potassium into water. (Exploded?) When she spilled hcl(I believe) she put vinegar on it for some reason. To write a purpose, I am trying to figure out the relationship between these things. Please help me.
