How many grams of a sodium salt would you need to prepare 500 ml of a buffer at pH = 3.29, using 0.100M solution. (Use 3 sig fig , atomic wts to whole number)
Nick, John. Why are you changing names? Answer: to pretend to not be dumping homework.
To calculate the number of grams of a sodium salt needed to prepare a buffer, we need to determine the molar concentration of the sodium salt required to achieve the desired pH.
First, let's understand the concept of a buffer. A buffer is a solution that resists changes in pH when an acid or base is added to it. It consists of a weak acid and its conjugate base or a weak base and its conjugate acid. In this case, we want to prepare a buffer with a pH of 3.29.
To create a buffer, we'll need a weak acid and its conjugate base. However, the given information only mentions a sodium salt, so we need to identify the weak acid corresponding to this salt. Once we know the weak acid, we can determine the molar concentration required to achieve the desired pH.
Could you provide the name or formula of the sodium salt so that I can proceed with the calculations?
