What are the limitations of using chemical indicators in determining the pH of a given solution?
tino4ka555 [31]

Answer:

1) chemical indicators won't work above it's pH range so therefore it probably won't change colour.

2) the solution should be clear and colourless to see colour change.

3) indicators tend to be of low accuracy so it's not 100% reliable.

Which solution contains the smallest number of moles of sucrose (c12h22o11, molar mass = 342.30 g/mol)? 2,000 ml of a 5.0 × 10–5
Iteru [2.4K]

> 2,000 mL of a 5.0 × 10–5% (w/v) sucrose solution 

5.0 × 10–3 g/mL * 2000 mL * (1 mol / 342.30 g) = 0.0292 mol

<span>
> 2,000 mL of a 5.0 ppm sucrose solution</span>

5 grams / 1000000 mL * 2000 mL* (1 mol / 342.30 g) = 0.0000292 mol

 <span>
> 20 mL of a 5.0 M sucrose solution </span>

5.0 M * 0.020 L = 0.1 mol
