Explain the neutralization of vitamin c with sodium hydrogen carbonate?

Scientists have known the consequences of mixing sodium bicarbonate and vitamin C ever since 1936, when a study on the subject was published in the "Journal of Nutrition." The authors of this study measured the amount of vitamin C recovered from the urine of people who drank a fixed amount of orange juice. The authors determined that the amount of vitamin C excreted was decreased by administration of sodium bicarbonate. Followup studies in the 1940s showed that this effect was due to the neutralization of the vitamin C by the sodium bicarbonate.

Vitamin c also known as ascorbic acid is neutralized by sodium hydrogen carbonate to form sodium ascorbate, carbon dioxide and water
 
ascorbic acid + sodium hydrogen carbonate = sodium ascorbate + carbon dioxide + water

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
