Asolution of sodium hydroxide is standardized against potassium hydrogen phthalate. from the following data, calculate the molarity of naoh solution. mass of khp used: 0.4536 g buret reading before titration: 0.23 ml buret reading at the end point: 31.26 ml

0.7158 Mol/L

Explanation:

KHC8H4O4 + NaOH → H2O + KNaC8H4O4

KHC8H4O4 molar mass = 204.2212 g/mol

0.4536 g of KHC8H4O4 = 2.221 mMol (10^-3 mol)

volume = 31.26 mL - 0.23 mL = 31.03 mL

NaOH concentration = 2.221 mMol/31.03 mL = 2.221 Mol/31.03 L = 0.7158 Mol/L

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
