1) perform proper calculations and explain what happens with red blood cells after immersing it in the solution composed of 1 g of glucose (180g/mole )
and 50 ml of water
2 ) explain shortly if The change in glucose concentration in the human blood influences ontcotic pressure
3 ) what will be the change in pH decrease or increase or no change of the water solution of ammonia during titration of this solution with HCL ? At what percentage from (0 to 100 %) , indicator used in this titration (mentioned in a point a ) will be dissociated at equivalence point in case of using methyl orange as indicator what will be the colour of the soultion at the end point of this titration ?
4 ) what will be the colour of phenolphthalein in the water solution of soduim aceate ? What is the role of water according to acid base bronsted theory in the occuring reaction .
5 ) a) out of Cu ,Ca, Zn,Pb ,Si ,I,N ,Ba,Fe,Mg,H,Cl
choose all elements from the above which ions can be detected by flame test and write what colors will be seen. In this this for choosen elements
b) choose one element which ion can be detected by using silver nitrate explain shortly how to perform such reactions and what will be the characteristics effect
c ) choose all macro elements of human body and write them in form of ions ; write in which body fluid (extra fluid or intracelluar ) they are higher concentration .
6) perform proper calculations or answer what kind of distrubance in acid -base equilibrium occurs when concentration of H+ in the human plasama is 4.8 .10*8 mol/dm*3 and concentration of HCO3 *-is 25mM;
7 ) a)calculate pH of 0.003 mol/dm*3 KOH solution ;
B) calculate pH and OH-ions conc in KOH solution after two times dilution of the solution from a point a(two times dilution means that equal volumes of KOH sloution and water were mixed .
