Equal volumes of 0.1M AgNO_(3) and 0.2M NaCI are mixed. The concentration of NO_(3)^(-) ions in the mixture will be

Answer»

`0.1M`
`0.05M`
`0.2M`
`0.15M`

Solution :`UNDERSET(0.1M)(AgNO_(3))+underset(0.2M)(NaCI) rarr AgCI +NaNO_(3)`
`0.1M AgNO_(3)` reacts with `0.1M NaCI` to produce `0.1M AgCI` and `0.1M NaNO_(3)`
`:. NO_(3)^(-) = (0.1M)/(2) = 0.05M`
`[ :'` When EQUAL volumes are mixed dilution occurs]
