Question

Mark statements as True or False
“Standard addition” method is used for individual samples with known sample matrices. ____________
(7). For Quant, a linear “Signal vs the concentration of analyte” response is not needed in Standard Addition
        Method and Internal Standard Method.___________
(8). The greater the Ka value,   the more dissociation the weak acid._______________
(9). In gravimetry, the use of a buret is for the volumetric analysis purpose. ________________
(10). The biggest buffer capacity lies in pH = pKa ( Ka is the dissociation constant of the conjugated acid ), even the
        buffer shows alkaline pH. ____________

(6). "Standard addition" method is used for individual samples with known sample matrices (7). For Quant, a linear "Signal vs the concentration of analyte" response is not needed in Standard Addition Method and Internal Standard Method (8). The greater the K, value, the more dissociation the weak acid. (9). In gravimetry, the use of a buret is for the volumetric analysis purpose. (10). The biggest buffer capacity lies in pH-pk. (K, is the dissociation constant of the conjugated acid), even the buffer shows alkaline pH. 10
