How would you know if enough base was added for the netralize reaction to be complete
By using the pH paper we can easily know enough base was added for the neutralize reaction to be complete because pH paper will show different colors at different pH value.
As we known that pH 1-7 is acidic , pH = 7 is neutral and pH-7-14 basic nature.
pH paper color:
Based on pH color we can decide neutralize reaction completed or not.
How would you know if enough base was added for the netralize reaction to be complete
n this experiment, you qualitatively added enough acid to neutralize all of the base in the basic extracts. Let’s put some numbers to this and use a quantitative analysis. Consider a situation where you are given 60 mL of 2.0 M NaOH solution. How many mL of 6.0 M HCl solution is needed to completely neutralize the NaOH solution? Show your work!
3. Given what you now know, what product(s) would you expect to isolate from this reaction? Y & NOT (NaO1-Bu) Specify how each of the following would affect the rate of the reaction. a. Increase the concentration of the base. b. Decreasing the concentration of alkyl halide.
How would the structure look if you added a small amount of p-divinylbenzene with the reaction of benzoyl peroxide and styrene?
How would you classify a Horner-Wadsworth-Emmons Reaction? A: acid base reaction B Esterfication Reaction C Pericyclic reaction D: Olefination reaction
How will you know how much Na2SO4 to add to dry the ether layer? A. When all of the liquid is gone you have added enough sodium sulfate. B. If the sodium sulfate looks "clumpy" you have added enough. C. All you need is a thin layer of sodium sulfate on the bottom of the beaker. D. When the sodium sulfate stops "clumping" and starts looking "powdery" you have added enough.

e) Would this reaction be considered an oxidation-reduction reaction? How do you know? 2. Enter the state symbols for following compounds (s, 1, g, aq). Then determine if they are a strong electrolyte and would dissociate (break into ions) in water (write yes or no). (4 pts) b) Ca3(PO4)2). ). a) Н2О ( c) HNO3 ΗΝO, ( ) d) Na2CO3)
how do I know if a compound is a base or an acid just by looking at its formula? i know how to determine acid and bases based on the whole equation, but it is hard to know just by looking at the compound, for example, Hco3, is it a base or an acid and how do we know, are there steps I can use? please give me examples with the explanation when I look at the formula for Hco3,...
