How do you compare values in KSP?

How do you compare values in KSP?

The greater the Ksp the more ions are in solution, hence the greater the molar solubility. However, you can only directly compare salts that give equivalent numbers of ions in solution. For example, you can compare the Ksp’s of all salts with a 1:1 ion ratio like: AgBr, BaSO4 etc.

What is little Q in chemistry?

Q is the energy transfer due to thermal reactions such as heating water, cooking, etc. anywhere where there is a heat transfer. You can say that Q (Heat) is energy in transit. Enthalpy (Delta H), on the other hand, is the state of the system, the total heat content.

How do you spell nernst?

Correct spelling for the English word “nernst equation” is [nˈɜːnst ɪkwˈe͡ɪʒən], [nˈɜːnst ɪkwˈe‍ɪʒən], [n_ˈɜː_n_s_t ɪ_k_w_ˈeɪ_ʒ_ə_n] (IPA phonetic alphabet).

What is meant by Nernstian behavior in an indicator electrode?

What is meant by nernstian behavior of an indicator electrode? If an indicator exhibits nernstian behavior, it follows the Nernst equation with its potential changing by 0.059/n V per ten-fold change in concentration. In amperometry, we measure the current in a cell at a fixed value of electrode potential.

What does an ion selective electrode measure?

Ion selective electrode (ISE) is an analytical technique used to determine the activity of ions in aqueous solution by measuring the electrical potential. It has wide concentration measurement range. As it measure the activity, instead of concentration, it is particularly useful in biological/medical application.

What is the most common ion selective electrode?

Ion-exchange resin membranes Ion-exchange resins are based on special organic polymer membranes which contain a specific ion-exchange substance (resin). This is the most widespread type of ion-specific electrode. An example is the potassium selective electrode, based on valinomycin as an ion-exchange agent.

How does an ion selective electrode work?

The ion-selective electrode works based on the principle of a galvanic cell. The transport of ions from an area of high concentration to low concentration, through the selective binding of ions with the specific sites of the membrane, creates a potential difference.

What is ISE test?

Trinity’s Integrated Skills in English (ISE) is a contemporary four skills (reading, writing, speaking and listening) qualification recognised by governments and institutions as providing reliable evidence of English language proficiency.
