State whether each of the following would increase, decrease, or leave the initial ph unchanged and explain your reasoning: using the same weak acid, but having a higher concentration. decrease the initial ph because having a higher concentration of weak acid is the same as adding more h+ into a solution which means there is more acid being added into a solution and because of this it will decrease the ph of a solution. using 80.00 ml of this weak acid instead of 40.00 ml. will not change the initial ph because having a greater volume of weak acid will not affect the concentration of weak acid (h+ ions). using a different weak acid that has a larger ka value. increase the initial ph because the larger the ka value the more concentration to dissociate into h+.
