Question

If a 0.2800 g of sample of Sodium Bicarbonate (96.5% NaHCO3) is titrated with 0.9165N Sulfuric Acid, what volume of the acid would be required to produce an endpoint?Show your solutions, thanks. ​

Answer 1

Answer: 3.51 ml

Step-by-step explanation:

% = V × N × MeWT / Sample weight

Volume is missing :

96.5% = (V?) × 0.9165N × 0.08041 ÷ 0.2800 g

= 0.9165N / 96.5 % × 0.2800 g

= 0.9165N / 0.2702

= 3.39 ml

Since 3.39 ml is not enough. Adjust the volume into 3.51 ml

Lets Check :

% = V × N × MeWT / Sample weight

= 3.51 × 0.9165N × 0.08041 / 0.2800 g

= 96.5 % (Round off)
