1/(1+23+12+48) x 100 = 1.2 %
The pH of sodium carbonate is around 11-12 due to its basic nature, while the pH of sodium bicarbonate is around 8-9 as it is slightly alkaline when dissolved in water. Both compounds are used as buffers and in various applications due to their pH properties.
For each element in NaHCO3, here is the breakdown: Sodium: 23/52 = 44% Hydrogen: 1/52 = 2% Carbon: 12/52 = 23% Oxygen 16/52 = 31%
12 divided by 142 is equaled to 12
The result of multiplying 142 by 12 is 1,704.
Dissolve 12 g dried sodium chloride (reagent grade) in 100 mL demineralized water.

To make a 2% sodium hypochlorite solution from a 12% solution, you can set up the equation: 12% solution * x litres = 2% solution * 100 litres Solving for x, you get: x = (2% solution * 100 litres) / 12% = 16.67 litres Therefore, you would need 16.67 litres of the 12% sodium hypochlorite solution to make 100 litres of a 2% solution.
