Calculate the hydrogen ion concentration in the following biological fluids whose `pH` are given below: a. Human muscle-fluid, `6.83` b. Human stomach fluid, `1.2` c. Human blood, `7.38` d. Human saliva, `6.4`. |
Answer» (a)`[H^(+)]` of human muscles fluid `pH=6.83 " or " - log [H^(+)]= 6.83 " or " log [H^(+)] =- 6.83 =bar(7).17` `[H^(+)] = " Antilog " [H^(+)] = " Antilog [bar(7).17] = 1.479 xx 10^(-7) M` (b) `[H^(+)]` of human stomach fluid `pH =1.2 "or " - log [H^(+)] =1.2 " or " log [H^(+)] =- 1.2` `[H^(+)] = " Antilog " (-1.2) = " Antilog (bar(2).8) =6.309 xx 10^(-2) M` (c) `[H^(+)]` of human blood `pH =7.38 " or " - log [H^(+)] =7.38 " or " log [H^(+)] =- 7.38` `[H^(+)] = "Antilog " (-7.38) = " Antilog"(bar(8).62) =4.168 xx 10^(-8) M` (d) `[H^(+)]` of human saliva `pH =6.4 " or " - log [H^(+)] =6.4 " or " log [H^(+)] =- 6.4` `[H^(+)] = " Antilog (-6.4) = " Antilog " (bar(7).6) =3.98 xx 10^(-7) M.` |
