0.16 gm of organic acid required 25 ml of (N)/(10) NaOH for complete neutralization. (M. wt of acids is 128). Then the basicity of acid is

Answer»


Solution :Equivalent acid = Equivalent of NAOH
`(wt)/("Gewt")= 25 XX 0.1 xx 10^(-3)`
`(0.16)/("Gewt") = 25 xx 0.1 xx 10^(-3)`
valancy(basicety) = `("Mol.wt")/("Gewt")=2`
