【Content determination】Take 10g of this product, quickly and precisely weigh, put in a 250ml measuring flask, add a new boiling cold water to dissolve the appropriate amount, let cool to room temperature, dilute with water to the scale, shake well, take 50ml with precision amount, put 500ml of stopper Erlenmeylene flask, add new boiling and cold water 95ml and 10% barium chloride solution 5ml, dense plug, shake well, leave for 15 minutes, add 2 drops of phenolphthalein indicator solution, titrate with hydrochloric acid titration solution (1mol / L) until the solution red disappears, Record the volume (V1) of hydrochloric acid titration solution 1mol/L), add 10 drops of methyl red-bromocresol green mixed indicator solution, continue to titrate with hydrochloric acid titration solution (1mol/L) until the solution changes from green to dark red, boil for 2 minutes, cool, and then titrate until the solution appears dark red
.

Record the volume (V2) of the hydrochloric acid titration solution (1 mol/L)
consumed.

According to the consumption volume (V1), the content of KOH in the test product is calculated, and the content of K2CO3 in the test amount is calculated according to the volume (V2-V1) consumed after adding methyl red-bromocresol green mixed indicator solution
.

Each 1 ml of hydrochloric acid titration solution (1 mol/L) is equivalent to 56.
11 mg of KOH or equivalent to 69.
10 mg of K2CO3
.

KOH 56.
11 [1310-58-3] This product is prepared by electrolysis
