Question
How many grams of $\mathrm{HCl}$ should be dissolved in sufficient water to get $500 \mathrm{ml}$ of an aqueous solution of $\mathrm{pH}, 2.0$ ?(a) $0.01$(b) $0.005$(c) $0.1825$(d) $0.365$
Step 1
0. We know that pH is defined as the negative logarithm of the concentration of hydronium ions (H+) in the solution. Mathematically, this can be written as: \[pH = -\log[H^+]\] where [H+] is the concentration of hydronium ions. Show more…

A solution is prepared by bubbling $15.0 \mathrm{~L}$ of $\mathrm{HCl}(g)$ at $25^{\circ} \mathrm{C}(298 \mathrm{~K})$ and $101,325 \mathrm{~Pa}$ into $250.0 \mathrm{~mL}$ of water. (a) Assuming all the HCl dissolves in the water, how many moles of $\mathrm{HCl}$ are in solution? (b) What is the $\mathrm{pH}$ of the solution?
How many grams are needed to make a solution that is 5 M HCl when you have 500 milliliters of water?
A solution of HCl has a pH of 2.50 . How many grams of $\mathrm{HCl}$ are there in $0.250 \mathrm{~L}$ of this solution? How many grams of $\mathrm{HCl}$ are in $250 \mathrm{~mL}$ of an $\mathrm{HCl}$ solution that has twice this $\mathrm{pH}$ ?
