The criterion used by the UNDP for measuring development is different from the one used by the World Bank in the sense that it uses a combination of factors such as health, education and income as indicators of development. It does not rely solely on per capita income, as is the case with the World Bank.what do you mean by development in what ways the criterion used by the World bank for measuring development different from the one used by UNDP discussAng mga sumosunod ay elemento bg kabutihang panlahat maliban sa
Determining the Strengths of Acids and Bases
Objectives:
1. Explain what dissociation constants explain about acids and bases.
Key Terms:
acid dissociation constant base dissociation constant salt hydrolysis reaction
Notes: (18-2)
You have probably noticed at some point that not all acids and bases are equally corrosive or harmful. This is because not all of them react the same in the presence of water. Acids and bases fall into the category of being either weak or strong bases on the following criteria.
Acids
Strong Weak
H+ ions transfers all in solution transfers only a portion in solution

The acid and base dissociation constant is the measure of the strength of the acids and bases.
The higher the dissociation constant the stronger the acid or base.
Since electrolytes are created as ions are freed into solution there is a relationship between the strength of an acid, a base, and the electrolyte it produces.
Strong acids and strong bases make strong electrolytes
Strong acid + Strong base neutral
Strong acid + Weak base slightly acidic
Strong base + Weak acid slightly basic
Weak acid + Weak base slightly acidic, slightly basic, neutralexplain how the strength of acid or base determinedHimesh BhaiHimesh ꧁࿇تتتتتت༒تتتتتت࿇꧂︻╦デ╤╾━ ✞’༄ᶦᶰᵈ᭄✿Gᴀᴍᴇʀ࿐꧁༺₦Ї₦ℑ₳༻꧂꧁☆☬κɪɴɢ☬☆꧂ᴬᴳ戀•ᴀssᴀsɪɴ•戀꧁༺nickname༻꧂The criterion used by the UNDP for measuring development is different from the one used by the World Bank in the sense that it uses a combination of factors such as health, education and income as indicators of development.
