### How do you make a 2 percent NaOH soluiton from 50 percent NaOH solution?

First you must either know how much 50% NaOH you want to start
with or know how much 2% NaOH you need at the end. Let's say you
want 1L of the 2% NaOH. Use this equation, and solve for x, where
in this case, x is the volume of 50% NaOH needed.
(50% NaOH)x = (2%) * 1000 ml
0.5x = 0.02(1000)
x = 20/0.5 = 40
Therefore, 40 ml of 50% NaOH in 960 ml water will produce 2%
NaOH. Use a 1000 ml volumetric flask to be most precise.

### How do you prepare a 50 percent solution of sodium hydroxide solution from 97 percent sodium hydroxide pellets?

Actually a 50% solution of sodium hydroxide would be made using
enough water to total 100 mL of solution if using sodium hydroxide
pellets or crystals. 50% of the total weight of the solution not
50% of the weight of the water used. As suggested by the first
answer, the solution would be about a 33% solution. percentage
solutions are weight for weight. Therefore 50% solution would be
50g of sodium hydroxide dissolved in 100g (100mL) of water.

### How do you convert gallons of 50 percent caustic soda into dry tons of caustic soda?

To calculate the Dry Short Tons (DST) from the solution of
NaOH50%, the net weight of the solution and percentage of sodium
oxide (Na2O) will need to be determined. Below is the
calculation:
(1) Pounds (lbs) of 50% solution x Na2O content (%) = Na2O
pounds
(2) Divide pounds of Na2O by 76% Na20 basis (.76) = NaOH dry
pounds
(3) Divide the dry NaOH pounds by 2,000 = NaOH Dry Short Tons
(DST)
