![]() = 5.0 moles glucose/ litre solution X 0.320 L solution Chemistry Interview Questionsħ) How will you calculate how many moles of glucose present in 320 mL of 5.0 M of glucose solution?įirst step: Convert the volume from millilitres to litres It is the amount of substance which consists of the same number of chemical units as there are atoms in exactly 12 gram of pure carbon-12. Mole is the unit used to define the number of chemical substance present in a substance. This will help your buffer to achieve a nearly equivalent amount of acid and conjugate base, so that it will enable to neutralize as much as H+ and OH. While when you select an acid as a buffer solution, try to use an acid that has a pH closed to your desired pH. On the overall pH of the buffer solution, these neutralization reactions will not show much effect. Hydroxide ion will be neutralized by the acid. In buffer when hydrogen ion is added, it will be neutralized by the base in the buffer. On adding a small amount of base or acid to buffer, its pH hardly changes. It is a blend of a weak acid and its conjugate base or vice versa.
