1. Find the molarity of 25g of sodium hydroxide dissolved in 1L of water. Identify the solute and solvent in this solution. please help me

.6250 M

The Sodium Hydroxide is the solute, and the water is the solvent.

Explanation:

mol/volume= Molarity

(25/22.99+16+1.008)/1=.6250 M.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
